摘要:
The invention concerns a light detection power system (105). The system can include a solar cell charging circuit (120) having at least one solar cell (116) in which the solar cell charging circuit can provide power to a power source (114), a lighting circuit (122) that receives power from the power source and a controller (118) coupled to the solar cell charging circuit and the lighting circuit. The controller can enable the lighting circuit when a power level that the controller detects from the solar cell charging circuit fails to reach a first predetermined threshold. The solar cell charging circuit can include a switch (130) that is controlled by the controller. The controller can further enable the switch when the power level that the controller detects from the solar cell charging circuit reaches a second predetermined threshold.

Wireless communications devices, such as cellular telephones (100), include an integrated camera (202) and process image data captured by that camera (202) to determine desired device illumination levels. A controller (410) within the wireless communications device (100) causes an image to be captured by the integrated camera (202). The captured image data is processed to determine approximate ambient light levels. A level of device illumination, such as provided by a display backlight (416) and a keypad backlight (418) is controlled based upon the approximate ambient light levels.
摘要:
A method (100) and system (10) for controlling ad-hoc membership in wireless networks to improve battery life includes determining (102) the capabilities of each of the members of a network and upon launching an application at a member, determining (104) a profile of members of the network required to support the application. A master device (12) can optionally disassociate (106) from the slave devices surveyed until an application is launched having a profile requiring a particular slave device. The method can further include associating (108) the members of the network in the profile and temporarily disassociating (110) a remaining group of members of the network. At another step (112), the method can also assign a higher priority to the members meeting the profile and assign a lower priority to the members that are temporarily disassociated and thereby reduce a maintenance cycle by probing the lower priority members less frequently.
摘要:
A peripheral component (104) is attached to a portable electronic device (102), and indicates an option class of the peripheral component by use of an option select circuit. The option select circuit causes an interrupt to be generated in the portable electronic device, which then determines the option class by changing the logic levels of various option select lines. If an inversion of the logic state of one of the option select lines is detected, then the portable electronic device knows an option select circuit is present, and determines the option class of the peripheral component accordingly.

An apparatus (102a) for causing an orchestrated rendering of pre-selected data content using a plurality of communications devices (102b-e) is provided. The apparatus includes a signal transmitting circuit (202) for transmitting a performance signal to at least one of the plurality of communications devices, the performance signal including a synchronization instruction. The apparatus additionally includes a synchronization module (208) communicatively connected to the transmitting circuit for generating the synchronization instruction. The synchronization instruction is based upon the pre-selected data content and causes the at least one communications device to perform a designated portion of the data content at a designated time during a rendering of the pre-selected data content.

A hazard defense system (100) includes a plurality of defense elements (104), and a controller (112). Each defense element can be located in an area (101) and each element includes at least one sensor (205) for monitoring at least one hazard and defense factor, a transceiver (202), and a processor (203) coupled to the at least one sensor and transceiver. The system is programmed to monitor (302) at least one hazard and defense factor, inform (304) the controller of the at least one defense factor, detect (306) a hazard at one or more defense elements, inform (308) the controller of the hazard, establish (310) an exit strategy at the controller according to the hazard and at least one defense factor, inform (312) the plurality of defense elements of the exit strategy, and direct (314) one or more individuals out of the area according to the exit strategy.

An electronic device (10) such as a mobile phone, a cellular phone, a two-way radio, a laptop computer, a portable stereo receiver, a portable television, or any combination thereof can include a cover such as a battery door cover (14) having a predetermined thickness and an aperture (16) within the battery door cover serving as an audio port for the electronic device and further constructed to serve as a bottle cap opener. The aperture can be for a high audio port (11) on a speaker phone for example. The aperture can be formed substantially towards an end portion of the battery door cover. The battery door cover can also be made of a rigid material such as plastic, metal or carbon fiber composite and can further include a sharp edge (17) to serve as a cutting instrument. Optionally, the battery door can further include a retractable or removable blade (19).

The invention concerns a method (200) and system (100) for flash control. The method can include the steps of—in a portable electronic device (122)—detecting (212) a request to operate a flash component (132), determining (214) whether to delay a timing of the operation of the flash component and if the timing will not be delayed, selectively disabling (224) a transmission component (114) for the portable electronic device. The selective disablement can create an operational opportunity (324) for the flash component. The method can also include the step of operating (224) the flash component during the created operational opportunity. As an example, the portable electronic device can be a mobile communications unit having a camera (136), the flash component can provide a flash for the camera and the transmission component can be a power amplifier (128).

The invention concerns a method (300) and system (100) for affecting gaming conditions based on at least one predefined parameter of a power source (126, 131). The method can include the steps of storing (312) the predefined parameter, in a first gaming unit (110) that receives power from the power source, providing (314) a gaming environment and detecting (316) the presence of the predefined parameter of the power source. The method can also include the step of altering (320) at least one gaming condition in the gaming environment based on the detected predefined parameter.
