The present invention relates generally to portable communication devices and more particularly to portable shoulder mountable communication devices that are adaptable to a variety of functional configurations.
Public safety environments, such as law enforcement and fire rescue, are increasingly seeking out improved approaches to managing a variety of portable public safety communication devices. In addition to managing such devices, there is an increased desire to provide additional functionality to a portable public safety communication device, such as video recording capability. Attempting to incorporate video technology into a portable public safety communication device presents design challenges associated with regards to size, weight, ruggedness, and ease of use. While there exist consumer type communication devices with video options, such devices do not typically offer architectures suitable to public safety applications. A public safety device that could be worn on the body and provide some level of hands-free functionality would be highly beneficial to public safety personnel. The ability of a public safety device to adapt to different functional configurations would enhance product customization for individual users and the various changing environments within which they work.
Accordingly, there is a need for a product architecture configurable to adapt multiple portable design derivatives for a wearable portable communication device.

The interchangeable bridge interface module 106 may comprise one of a camera interface module 110 and a non-camera interface module 120. The camera interface module 110 provides for a camera interface connection between the RSM 104 and power source module 108. The non-camera interface module 120 provides for a non-camera interface connection between the RSM 104 and power module 108.
In accordance with the embodiments, the camera interface module 110 may comprise a full spherical video camera module 116 or a hemispherical video camera module. Either module, coupled between the RSM 204 and the power source module 208, provides video capability to the portable communication device 102.
In accordance with some of the embodiments, the power source module 108 may be interchangeable and comprise a portable battery 112 or a corded power source 114. The corded power source 114 may originate from a power source worn on a belt or distributed elsewhere on the body. Hence, the corded source 114 is said to acquire power from an external body-worn battery.
In accordance with the embodiments, the portable communication device 102 comprising remote speaker microphone (RSM) 104 is adaptable to receive at least two interchangeable modules, the at least two interchangeable modules and the RSM 104 being powered by the power source module 108. The at least two interchangeable modules may comprise the camera module 110, for coupling between the RSM 104 and power source module 108, and may comprise the non-camera interface module 120, for coupling between the RSM 104 and power source module 108. In accordance with some embodiments, the power source module 108 may be an interchangeable module which is interchangeable between a portable battery 112 and a corded power source 114. The portable communication device 102 provides a portable, body wearable device for shoulder worn applications particularly well suited to public safety environments, such as law enforcement and fire rescue.
The portable communication device 202 is formed of front, middle, and back portions respectively configured in a reverse u-shape formation for shoulder mountable applications. The portable communication device 202 comprises a portable, body wearable device for shoulder worn usage particularly well suited to public safety environments, such as law enforcement and fire rescue. All of the portable operational design derivatives 230, 240, 250, 260, and 270 of
The RSM 204 comprises a speaker, a microphone, and a push-to-talk (PTT) button, all under the control of one or more internal processors and interoperable with an internal transceiver in a known manner. In accordance with the embodiments, the power source module 206 powers the RSM 204 through interconnection within the bridge interface module 206 when a non-camera bridge interface 220 is coupled between the RSM 204 and the power source module 206. The power source module 206 powers the RSM 204 and additionally powers circuitry associated with the camera when the camera bridge interface module 210 is coupled between the RSM 204 and the power source module 206.
The portable communication device 202 comprises a remote speaker microphone (RSM) 204, a power source module 208, and an interchangeable bridge interface module 206 coupled therebetween. In accordance with the embodiments, the interchangeable bridge interface module 206 comprises a plurality of interchangeable interface bridge modules, each adapting the RSM 204 to the plurality of portable operational design derivatives 230, 240, 250, 260, 270.
The interchangeable bridge interface module 206 may comprise a camera interface module 210 and a non-camera interface module 220. The camera interface module 210 may comprise a full spherical video camera interface module 216 or a hemispherical video camera interface module 218 for bridging between the RSM 204 and power source module 208. The non-camera interface module 220 provides an interconnect bridging between the RSM 204 and power source module 208. Hence, the plurality of portable operational design derivatives comprise: RSM with full spherical video camera, RSM with hemispherical video camera, and RSM with bridge interface without video camera, each powered by power source module 208.
In accordance with some of the embodiments, the power source module 208 of the portable communication device may also be interchangeable and comprise a portable battery 212 or a cabled power source 214. The cabled power module 214 may acquire power from, for example, a vehicular battery source or other remote power source available within the public safety environment.
As previously stated, the portable communication device 202 is formed of front, middle, and back portions respectively configured in a reverse u-shape formation for flexible shoulder mountable applications. The RSM 204 forms the front portion of the portable communication device 202, the bridge interface module 206 forms the middle portion of the portable communication device, and the power source module 208 forms the back portion to the portable communication device.
Wearable studies have concluded that rear shoulder blade surface area drops off quickly from the apex of the shoulder, thereby creating limited area for device length. While the power source module 208 embodied as a corded power source 214 is configured to minimize the length that extends down the back portion of the device, the portable battery 212 presents additional challenges in terms of size and weight.
In accordance with the embodiments, the power source module 208 embodied as the portable battery 212 is advantageously configured to minimize rearward projection for shoulder worn applications. The rearward projection of the portable battery 212 is minimized through the use of a reverse T-shaped configuration in which a vertical portion of the reverse T-shape is coupled to the bridge interface module 206 and a horizontal portion of the reverse T-shape is at the back end portion. When the portable battery 212 is coupled to the bridge interface module 206, the bridge interface module 206 extends the vertical portion of the T-shape. This allows the weight of the portable communication device 202 shown in operational design derivatives 230, 240, and 250 to be evenly distributed between the RSM 204, interface bridge module 206 and portable battery 212. The use of the reverse “T” shaped configuration for the portable battery 212 allows for maximized battery capacity without extending the device too far back on the back shoulder. In other words, configuring the bridge interface module 206 and the portable battery 212 to interconnect in a reverse T-shape configuration above the apex of the shoulder avoids physical interference of the battery with an external object, such as a vehicle seat, while maximizing battery capacity.
In some embodiments, a wireless charging energy coil (not shown) would be in proximity to the portable battery 212 for wireless charging. Wireless charging, such as from a corresponding transmit charging coil, located in a vehicle may provide for vehicular charging options of the portable battery 212.
For other operational design derivatives 260, 270, 280 in which the power source module 208 is embodied as corded power source 214, an optimal distribution of weight is achieved based on the corded power source module 214 not extending too far back on the user's shoulder, thereby advantageously minimizing interference between the shoulder mounted device and other objects, such as a vehicle seat.
In some embodiments, an optional flexible interconnect module 222 may also be coupled between the RSM 204 and the interface bridge module 206 to provide additional flexibility and conformability for the battery powered devices, if desired. For the corded power source derivatives, 260, 270, the flexible interconnect module 222 is removed which permits positioning of the RSM 204 higher on the front of the shoulder which provides balance with the shorter corded power source module 214.
The portable communication device is preferably embodied as a public safety communication device that can be worn on the body and provide access to RSM controls while providing hands-free video functionality which is highly beneficial to public safety personnel. The ability of a public safety device to adapt to different functional configurations comprising camera and non-camera modules as well as different power source options, battery and corded, enhances product customization for individual public safety use cases.
The portable RSM communication device provided by the various embodiments provides significant advantages over standard RSMs in terms of better weight distribution and increased real estate resulting in improved ergonomics and increased functionality. A user can advantageously use the standalone RSM functionality of operational design derivative 250, while maintaining the option to interchange the non-camera bridge interface module 220 with a camera bridge interface module 210 as the need arises. A variety of interconnect mechanisms, known or yet to be developed, can be used for the attachment and detachment of the modules. The interchangeable power modules, and/or flexible interconnect modules provide a further level of product customization. Hence, the portable communication device provides a configurable wearable architecture that is be particularly useful for public safety personnel that move amongst different environments.
Hence, the various embodiments of the portable communication device shown and described, provide for a shoulder mountable RSM with a dedicated power source along with modular adaptability for accepting interchangeable bridged interface modules between the RSM in the form of a camera module and a non-camera module and the power source in the form of a portable battery and a corded power source.
In accordance with the embodiments, the RSM 204 forms a front portion of the portable communication device 230, interface bridge module 206, forms a middle portion of the portable communication device 230, and the power source module 208 forms a back portion of the portable communication device 230. The portable communication device is formed generally in a reverse u-shape that is well suited to shoulder mountable applications and allows the device to provide a close to the body form factor. The embodiments of the portable communication device advantageously negate any need for protruding or extended parts. The RSM 204 conforms to a front shoulder portion 804, the interface bridge module 206 conforms to a top shoulder portion 806, and the power source module 208 conforms to a back shoulder portion 808.
The various embodiments of the portable communication device provide significant advantages over standard RSMs in terms of improved weight distribution by locating the power source to conform to a back shoulder portion 808. The power source module 208, embodied as a portable battery in reverse T-shape, is sized and shaped to minimize rearward projection and thus well suited for applications in which the user is seated in a vehicle. With the camera interface module 210 is coupled between the power module 208 and the RSM 204, the user can advantageously utilize RSM controls, such as push-to-talk (PTT) and volume control, while capturing video via camera interface module 210 simultaneously.
The modular interface providing interchangeable modules between the RSM 204 and power source module 208 allows a user to have the option of RSM-only operation and RSM-video recording operation. The interchangeable modules provided by the various embodiments may be attached to and removed from the RSM 204 to form a portable communication device customized to a customer's usage requirements. The attaching and detaching of the modules may be factory configured or user configured. For example, in some embodiments, when video recording is no longer desired, the camera interface bridge module can be removed and replaced, to change to a non-camera bridge interface module 220, shown in
Accordingly, there has been provided a portable, body wearable communication device that can accommodate a plurality of different modules, such as a video camera and/or power module. The embodiments have provided for a shoulder mountable portable public safety communication device that advantageously provides a RSM with interchangeable camera and non-camera bridge interface modules. The embodiments have further provided portable battery or corded power modules.
