The present disclosure relates generally to portable communication devices and more particularly to status indicators for portable radios.
Portable communication devices, particularly portable two-way radios, typically offer several features and controls on a single handheld device, such as channel change knobs, one or more displays, volume control, keypad and push-to-talk (PTT) button. Traditionally, portable two-way radios used in the public safety environment include channel change controls with channel indicators in the form of numbers or letters disposed around the channel knob and/or displayed on the display. The use of portable two-way radios in other types of environments, such as business environments, is increasing in popularity as a means of increasing productivity and efficiency in the workplace. Adapting the portable two-way radio to the needs of these new users is both desirable and challenging.
The manner in which portable two-way radio devices are used depends on what type of individual is operating the device, and the type of environment within which the device is being operated. For example, a public safety employee working in a public safety environment may be familiar with and require multiple operating features and controls on a single device. Other users, such as employees working in retail environments or restaurant environments may have completely different outlooks and expectations of how a portable two-way radio should be incorporated within their workspace. In business type environments, a smaller, more streamlined and scaled down product may be desirable. Providing a user-friendly interface presents a challenge when integrating numerous features and controls on a smaller size device. The need to balance the sophistication of controls and features on a portable two-way radio thus varies with different types of users and user environments.
Accordingly, it would be beneficial to have a user interface for a portable two-way radio directed towards a business environment, such as a retail or restaurant environment.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method, steps and apparatus components related to providing a portable communication device with a user friendly interface. The portable communication device is a streamlined, palm sized device having no display and no dedicated channel control knob. The user interface formed in accordance with the embodiments described herein is well suited for such a device. To this end, the portable communication device comprises a housing having electronics. A single multicolor generating light emitting diode (LED) is coupled to the housing and electronics to provide a plurality of radio status indicators, including channel status, transmit mode, receive mode, and battery status. A combination of predetermined LED colors and predetermined pulsing or blinking rates allows a user to have a visual indication of the radio's status. A menu button in conjunction with a volume up/down button is used to control channel change. A power button is used to enable the battery status check. Thus, use of the single multicolor LED allows for a compact radio form factor that allows visual feedback of the radio status without the use of a display and without the use of a dedicated numbered or lettered channel control knob.
In the description herein, numerous specific examples are given to provide a thorough understanding of various embodiments of the invention. The examples are included for illustrative purpose only and are not intended to be exhaustive or to limit the invention in any way. It should be noted that various equivalent modifications are possible within the spirit and scope of the present invention. One skilled in the relevant art will recognize, however, that an embodiment of the invention can be practiced with or without the apparatuses, systems, assemblies, methods, components mentioned in the description.
Portable radio 100 further includes volume up-down button 106, an accessory connector 108, and a push-to-talk (PTT) button 110, as shown in
In accordance with some embodiments, the menu button 114 in conjunction with the volume up/down button 106 enables channel change control, while the power button 104 enables power on, power off and battery status. The single multicolor LED 102 is responsive to these predetermined button presses to provide radio status indicators. In accordance with the embodiments, the single multicolor LED 102 provides portable radio status in the form of battery status and a channel status by illuminating different colors and different pulsing rates.
The battery status can be checked by pressing the power button 104 for a predetermined amount of time. A short power button press is used to check the battery status, while a longer power button press turns the radio on and off. In response to the power button 104 being pressed, the multicolor LED 102 glows for a predetermined amount of time with a predetermined color to represent battery status. Examples of predetermined colors for the battery status are provided below:
Green—high level battery charge
Yellow—medium level battery charge
Red—Low level battery charge
Red blinking—critical low level battery charge
Once the portable radio 100 is turned on and battery status has been indicated by LED 102, the LED automatically begins pulsating the current channel color. The current channel color can be viewed by the user as well as others working in the same environment.
In order to change channels, a user presses the menu button 114. Each press of the menu button 114 results in an audio announcement announcing the various menu settings, such as channel, monitor, scan and call tone. Pressing the PTT 110 will exit the menu or alternatively, a time-out timer within the radio will also exit the menu.
Once the channel announcement is made, the volume up-down button 106 is used to select the channel setting from a plurality of color coded channel settings.
Accordingly, radio status indicators are automatically provided by pulsing the LED 102 using a single color at a first predetermined rate to indicate the current channel; pulsing the LED at a second predetermined rate to indicate receive mode; presenting a solid LED color to indicate transmit mode; and changing the LED color to indicate a change in channel. Thus, use of the single multicolor LED allows a compact radio form factor with visual user interface. The use of the single multicolor LED 102 in conjunction with the power button 104 to provide battery status, and the use of the single multicolor LED 102 in conjunction with the menu button 104 and volume up/down button 106 to control channel change provide for multiplexed controls which minimize the number of overall controls needed for the radio's compact form factor. The status of other menu options can also be enabled via the menu button 104 and visually represented by LED 102. For example, a radio having a scan mode can have the scan mode enabled by pressing the menu button 114 until a scan announcement is made which will result in the LED 102 scrolling through all the colors associated with the various channels. Thus, the use of multiple colors from the single multicolor LED 102 provides a user with a friendly visual approach to operating the radio.
At 406, the LED 102 is pulsed at a second predetermined rate to indicate receive mode at 406. The LED 102 emits a solid (non-pulsed) color during transmit mode at 408. Transmit mode is enabled as a result of the PTT being pressed. Battery status is checked at 410 by pressing the power button 104 for a predetermined amount of time. This power button press is a “short” keypress as compared to the power up or power down keypress. At step 412, the color of the LED 102 changes in response to a channel change being made. The channel change is made by having the user press the menu button 114, listen for the channel option, and then scroll through the channels using the up/down buttons 106 to select the desired color coded channel. Other menu options can be assigned to predetermined color and pulsing configurations of LED 102.
Accordingly, there has been provided a portable communication device which facilitates communication needs in a variety of environments, such as restaurant and retail segments. The use of the status indicator formed in accordance with the embodiments, provides a utility radio with a user interface having a personal, palm-sized device which redefines the traditional form factor by including only essential elements within the radio. The portable communication device is smaller and lighter than other radios in its class. The status indicator provides an easy to interpret user interface in the form of channel change and battery status with the benefit of reduced cost achieved by the removal of the display and channel control knob. Channels are associated with color instead of numbers or letters by a single multicolor LED. Using the status indicator to illuminate the product logo provides a further benefit of brand identification.
