Abstract:
A mobile communication device (106) comprising a transceiver (202), and a processor (203) coupled to the transceiver. The processor is programmed to enter (304) an emergency mode corresponding to an alteration type of an element of the mobile communication device, and process (306) messages according to the emergency mode.
Abstract:
A charger determines the voltage baseline (204) of a battery and establishes a voltage range based on the voltage baseline of the battery. Once the rapid charge rate has terminated (212) and the trickle charge rate commenced (214), the charger monitors the voltage of the batery (218) in order to make sure the battery is not being depleted. If the battery voltage is above the established range (220), the trickle charge rate is decreased (222), and if the battery voltage is below the voltage range (224), the trickle charge rate is increased (226).
Abstract:
A method (400) for allocating handoff of mobile stations (105, 110) to a first network node (115). The method can include receiving a handoff request for a first mobile station. Handoff of the first mobile station can be granted in response to determining that the first mobile station has an effective level of battery charge equal to or below a threshold value. Handoff of the first mobile station can be denied in response to determining that the first mobile station has an effective level of battery charge greater than the threshold value. The method also can include receiving status information (130) communicated by the first mobile station. The status information can indicate an effective battery level of the first mobile station. In another arrangement, the status information can indicate a handoff priority level of the first mobile station
Abstract:
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.
Abstract:
The invention concerns a method (300) and system (100) for affecting gaming conditions based on operating conditions of a power source (126). The method includes the steps of - in a first gaming unit (110) that receives power from the power source - providing (312) a gaming environment and monitoring (314) at least one operating condition of the power source. When at least one of the operating conditions reaches a predetermined threshold, the method further includes the step of altering (320) at least one gaming condition in the gaming environment to indicate to a user that the operating condition has reached the predetermined threshold.
Abstract:
The invention concerns an apparatus (100) for indication of a charging condition. The apparatus includes an indication circuit (126) having at least one electromagnet (120) and a charge control circuit (128) for controlling charging current to a portable device (110). The indication circuit causes the apparatus to electromagnetically engage the portable device and the charge control circuit provides charging current to the portable device during the engagement. The indication circuit also causes the apparatus to electromagnetically decouple the portable device when the portable device is charged to a predetermined level to permit a user to remove the portable device from the apparatus.
Abstract:
A battery pack (110) having a plurality of cells (103, 105) utilizes a pull up resistor (116) multiplexed between separate voltage supply sources (120, 122) and a single battery contact (106) to monitor individual cell temperatures. A plurality of thermistors (102, 104) are coupled in series between ground potential (108) and the single battery pack contact (106), each thermistor being coupled to one cell of the pack. Individual voltage divider circuits are formed for each thermistor (102, 104) as the pull up resistor (116) is multiplexed between the voltage supply sources (120, 122).
Abstract:
A system (200) includes a visiting wireless device (202) and a host wireless device (206) that communicate with each other. A shared user interface is commonly used by the two devices. During an ongoing interaction between a user of the visiting device (202) and a user of the host device (206), images of each user (106 and 108) are communicated to the other device and both devices display the images of both user. Through updates images communicated back and forth between the devices, the users “virtually” interact with the shared user interface. A permission level restricts the interactions available to the visiting device (202).
Abstract:
A method is provided for adjusting power consumption in a device 200. According to the method, a command 400 to enter a low power mode is received, and, in response to receiving the command 400, at least one operating mode of the device 200 is adjusted so as to enter a low power operating mode. In one embodiment, the at least one operating mode that is adjusted includes at least one of a quality of service setting, a vocoding ratio, a BER threshold that initiates background scanning, a frequency of monitoring other communications networks, a definition of a function key, an operating mode of a display, a resolution of a display, a sensor, a CPU clock speed, and an alert time.
Abstract:
The invention concerns a method (800) and system (100) for generating characters on a display. The method (800) includes the steps of assigning (812) at least one character (124) to one of a plurality of predetermined values that correspond to varying levels of pressure and receiving (816) an applied pressure. The method (800) can also include the step of selecting (820) at least one character (124) in response to the applied pressure in which the character (124) that is selected is assigned to the predetermined value that corresponds to the applied pressure.
