The present invention relates to information systems and in particular a portable system configured to be deployed in a computer network.
U.S. Pat. No. 6,438,577 ('577 patent) discloses a portable network including a server and a plurality of computing devices assembled in a briefcase. Specifically, the '577 patent discloses a briefcase having exterior walls and interior walls. The interior walls define a space for receiving the computing devices, while the space between the interior walls and the exterior walls are used for housing other components such as the battery, the power supply, the hard disk, the server and other components.
As is well known, electronic components such as power supplies, processors, and computing devices generate heat during operation. For example, a portable computer may heat up while charging, and the power supply that supplies the charge to the portable computer also heats up while charging the battery of the portable computer. The heat so generated must be dissipated. Otherwise, malfunction may occur. Typically, the heat so generated is released to the ambient environment as air usually takes the heat away from the heated component. However, the configuration proposed by the '577 patent packs all components tightly next to one another, which restricts the circulation of air. Furthermore, in the configuration shown by the '577 patent the region defined for receiving the computing devices is separated from the region defined for receiving the components of the server by interior walls. Thus, heat cannot flow easily from a high temperature region to a low temperature region in order to escape. In short, the arrangement proposed by the '577 patent creates heat transfer barriers and heat traps, which may adversely affect the operation of the components.
On the other hand, in a system according to the present invention, a housing is provided to allow for the free flow of air to avoid internal barriers to the transfer of heat from a high temperature region to a low temperature region in order to prevent the generation of heat traps that may cause malfunction.
In the first embodiment, an open internal frame work is used to support panels of the housing and the components. The internal frame work allows for the circulation of air among the components of the system and even the computing devices, and the air so circulated can be cooled by, for example, heat dissipation from the external panels of the housing.
In the second embodiment, the housing has an open interior as well allowing for circulation of the air among the components and the computing devices. In the second embodiment, the housing structure itself is configured to have a region or regions for heat spreading by direct thermal connection to the heat generating component(s).
A system according to the present invention includes a portable housing having a section for receiving a plurality of computing devices. The housing defines a space for a plurality of components that are configured to provide power and information to the computing devices, the components including at least a power supply, a processor, and a router (preferably wireless). The housing is configured to allow for circulation of air among the components and the computing devices received in the section for receiving the plurality of computing devices. In a system according to the present invention the components further include a charger circuit, a non-volatile memory, input/output connectors, and at least one rechargeable battery.
The housing may include a fascia panel having a plurality of elongated slots each configured to receive a respective computing device and to guide the computing device so received into the section for receiving the plurality of computing devices. The fascia panel is preferably positioned opposite a support wall that supports a plurality of connectors, each connector being configured for connection to a respective computing device. Each slot in the fascia plate may be associated with a visual indicator.
In a system according to the present invention, each connector may be mounted on the support wall with a respective connector support, which connector support positions and orients its associated connector for connection to a power input connector of a respective computing device.
Each connector may be associated with a connector assembly and each connector assembly may be associated with a respective releasable stop assembly.
Each releasable stop assembly may include a movable stop which when pushed toward the support wall by a computing device will move until reaching a stop position to prevent further advancement of the computing device.
Each releasable stop assembly may be configured to release the stop when the stop is pushed toward the support wall after it has been locked.
Each stop may be spring loaded, or magnetically locked and releasable.
Each stop may be associated with a respective lock assembly. Each lock assembly may include a rotatable catch that cooperates with a latch to prevent the stop from moving toward the support wall.
Each lock assembly may be configured to prevent mismounting of a computing device.
In the first embodiment, the housing includes an internal open framework supporting a plurality of panels that define the portable housing.
A system according to the second embodiment includes a portable housing having at least one metallic tray. The portable housing houses therein a plurality of components that are configured to provide power and information to a plurality of computing devices, the components including at least a power supply, a processor, and a router (preferably wireless), wherein at least one of the components is thermally coupled to the metallic tray.
The housing of the second embodiment may further include a fascia panel having a plurality of elongated slots each configured to receive a respective computing device and to guide the computing device so received into a section for receiving the plurality of computing devices inside the housing, the fascia panel being positioned opposite a support wall that supports a plurality of connectors, each connector being configured for connection to a respective computing device. Each slot in the fascia plate may be associated with a visual indicator.
Preferably, a system according to the second embodiment includes another metallic tray arranged opposite the metallic tray. At least another one of the components may be coupled to the another metallic tray. The metallic tray and the another metallic tray are preferably arranged on opposite sides of the section for receiving the computing devices. The metallic trays may have identical exterior appearances.
The metallic tray (or trays) may include a plurality of vent holes allowing air to pass from interior of the housing to the exterior of the housing. An electric fan may be installed adjacent the vent holes.
Preferably, the metallic tray is comprised of aluminum as it is visually pleasing, is light weight, and it is a good conductor of heat.
Other than its housing, the second embodiment would includes the same internal features such as the connector assemblies, the stop assemblies, the lock assemblies, and the same components as those in the first embodiment.
Other features and advantages of the present invention will become apparent from the following description of the invention which refers to the accompanying drawings.

Between power supply 12 and charging circuit 14 is a power distribution board 15 that connects to one of the outputs from power supply 12 and the batteries. Board 15 when receiving power from power supply 12 will route it directly to charging circuit 14 for the computing devices 30 (e.g. iPads) while also charging the batteries. Without external power the output from the batteries are routed to charging circuit 14.
Modem 24, when available, can be connected to a publicly accessible network (e.g. Internet). In one preferred embodiment, modem 24 may be connected to an antenna 24′ which is configured to connect modem 24 to a satellite for satellite Internet connection. GPS related information may be obtained via the satellite connection. Moreover, wireless router 20 may be configured for connection to another, local computer network 24″. For example, when deployed in an aircraft having a resident local computer network 24″ with Internet connection capability, router 20 may connected to network 24″. System 10 may be further provided with other input/output connectors 28 (e.g. USB connectors) for connection to cameras and other sources of electronic information and data.
Non-volatile memory 18 may be a hard drive, a solid-state electronic memory storage device, or any other information storage device which can be loaded or is preloaded with computer readable files.
For example, memory 18 may be loaded with moving pictures in digital format or games. In addition, maps or other information may be loaded into memory 18.
Processor 16 may be a conventional CPU suitable for service in the capacity of a server to provide processing service for a plurality of client devices.
Wireless router 20 is configured for short-range (e.g. less than 30 meters) wireless transmission of electronic information preferably in a digital format.
Charger circuit 14 is connected to a plurality of power connectors 22 residing within system 10. Each power connector 22 is configured to connect to the power input receptacle of a mobile computing device such as a tablet computer. Once a connector 22 is electrically connected to a power input connector of a mobile computing device, charger circuit 14 supplies power to the connected mobile device in order to recharge the on-board battery thereof. In the preferred embodiment, mobile computing devices capable of connection to connectors 22 are wireless computing devices 30 such as iPads® or the like devices.
In operation, a wireless device 30 may request a file (e.g. a movie or a game) from system 10. The request so made is received by wireless router 20, passed on to processor 16, which then retrieves the requested file from memory 18 and sends (e.g. streams) the requested file via wireless router 20 to the requesting wireless device 30. A wireless device 30 may also access the Internet through system 10 preferably the same way a client computer can access the Internet via a server in a network.

Preferably, connector assembly 64 is adjacent a releasable stop assembly 70. Each releasable stop assembly 70 includes a movable stop. When the stop of a releasable stop assembly 70 is pushed toward support wall 62 by a device 30 that is in the process of being stored, the stop locks at a predesignated stop position to stop device 30 from further advancement into the storage section. The stop position of the stop is selected to ensure proper engagement of its associated connector 22 with the power input receptacle of device 30.
Each releasable assembly 70 is preferably configured to release the stop when pushed toward support wall 62 a second time by the stored device 30. The stop is preferably spring-loaded so that upon being released it pushes the stored device 30, with which it is in contact in its engaged state, away from support wall 62. Alternatively, the stop may be magnetically coupled so that it may be releasable.
Optionally, a clamp or the like device may be associated with the releasable stop 70 to prevent a stored device 30 from being withdrawn unless stored device 30 is first pushed toward support wall 62 to disengage the clamp. Thus, in this optional configuration, the clamp engages the stored device 30 once the stop reaches its stop position for additional security. Preferably, the stop and the clamp assemblies are based on a push-push mechanism usually employed in automotive applications.
Preferably, each slot 50 is adjacent a respective visual indicator 72. Once a device 30 is properly received in its stored position and properly connected to a connector 22 associated with said slot 50, the associated visual indicator is operated to inform the user of a successful connection.

A suitable application for a system 10 according to the present invention is a combination server and recharging station for an in-flight entertainment system. Such a system 10 may be configured to be compact enough to fit behind a seat on a plane and receive power from an outlet provided in the plane.
System 10 may be loaded with movies or other media that can be streamed to wireless devices 30 on demand over the built in wireless network. System 10 can also be connected to outside information sources such as the World Wide Web via an Internet connection, a camera that provides images from outside of the plane while in flight, or a source of avionics data. Information from the external information sources may be then shared with the passengers via router 20.
A system 10 according to the present invention may also be configured to serve as a USB hub allowing synchronization to computing devices 30 (e.g. iPads) without removing them from system 10.
According to one embodiment, system 10 is configured to allow reception of a device 30 in one orientation, thus ensuring that device 30 is properly aligned with a connector 22.
To prevent stop 71 from moving toward wall 62, a releasable lock assembly 75 is associated with stop assembly 70. Releasable lock assembly 75 includes a rotatable catch 77, which is rotatably mounted on support bracket 73. Rotatable catch 77 includes a blind slot 79, which receives a latch 81 mounted on stop assembly 70. Latch 81 abuts the blind end 83 of slot 79, which prevents stop assembly 70 from moving toward wall 62. Once catch 77 is rotated so that blind end 83 of slot 79 no longer abuts latch 81, then stop assembly 70 is allowed to move toward wall 62.
Specifically, a groove 87 (see
The lock assembly 75 prevents the mis-mounting of a device 30 as follows.

As mentioned earlier a system according to the present invention is particularly suited for use on an aircraft. The system's portability allows it to be easily moved between aircrafts. The system is easier and cheaper to install and not subject to as many regulatory requirements. Furthermore, the system can be more easily and cheaply updated if necessary while an installed systems for an aircraft will have to adhere to original specifications as they were certified.
A system according to the present invention is best suited for environments that lack easy and inexpensive internet access such as an aircraft or a boat. In an aircraft, internet access is very expensive both for the hardware and usage. An installed (non-portable) system that can provide the functionality of a system according to the present invention can easily cost over $250,000 to install, and its usage can cost tens of thousands of dollars in just one flight.
In addition, there are few if any airborne systems that have the bandwidth that would allow multiple users to stream media like movies. By keeping this media on the aircraft itself and avoiding the requirement for internet streaming, a system according to the present invention allows more users to enjoy the media that would otherwise be possible with a conventional, installed system, while lowering the costs.
By keeping the media on the system, it is not necessary to have each computing device loaded with up to date content. In addition using a central server allows for more storage capacity that would normally be available on computing devices 30 (e.g. iPads). The system also saves costs by avoiding the expense of increasing the storage capacity of individual computing devices. Rather, the non-volatile memory could be replaced with another memory of larger capacity, another non-volatile memory could be added, or an external non-volatile memory (another hard drive) could be simply connected to the system via one of the Input/Output ports.
While the embodiments shown herein include one battery, a plurality of batteries may be provided, each, for example, providing charge for a respective computing device.
The system, in its preferred form for use on an aircraft, may be 10.5×12.25×7.5 inches and about 15-25 pounds. The dimensions of the system are selected so that it may fit behind a seat in an aircraft or under a seat in an aircraft. Thus, the dimensions and the weight may be varied as long as the system remains suitable for portability (can be carried by a person) and used on an aircraft.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
