Patent number: 7382270Abstract: An apparatus supporting both identification of a battery type and communications over an interface between a battery and an electronic device is disclosed. The electronic device includes a processor for communicating with communications circuitry of the battery. Identification circuitry associated with the processor enables a determination of the type of battery with which the electronic device is connected. If a “smart” battery capable of carrying out serial communications with the electronic device is connected, the electronic device further provides means for carrying out communications between the processor and the communication circuitry of the battery.Type: GrantFiled: February 24, 2006Date of Patent: June 3, 2008Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Heino Wendelrup, Magnus Hansson

Patent number: 7376487Abstract: Disparate robotic devices can be automatically recharged and reprogrammed by self-scheduling individual time slots for the available recharging area(s) of a charging station. These charging stations provide a nest to which each robot must return periodically for power. These nests can also provide new tasking or patches for the robotic devices. The charging station and the robotic devices are both provided with communications capabilities and a protocol by which they can negotiate to find a time slot in which the device can be recharged, as well as determining a correct connector and a battery type.Type: GrantFiled: November 25, 2003Date of Patent: May 20, 2008Assignee: International Business Machines CorporationInventor: David Bruce Kumhyr

Patent number: 7339485Abstract: Disclosed is a rectifier for supplying double voltage and an RFID tag thereof. The rectifier includes a charging part for charging an input voltage induced to input ends by a received radio frequency (RF) signal; a power provider for charging a sum voltage corresponding to the sum of the input voltage induced to the input end and the voltage charged in the charging part as a power voltage, and discharging the charged power voltage to provide a direct current (DC) power; and a switching part for switching to supply the input voltage induced at the input ends to the charging part during a first interval and switching to supply the sum voltage to the power provider during a second interval. Accordingly, double voltage can be supplied to other electric elements formed in the RFID tag and overcurrent caused by overvoltage can be prevented from flowing into the elements.Type: GrantFiled: February 17, 2006Date of Patent: March 4, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Ja-nam Ku, Young-hoon Min, Il-jong Song, Dong-hyun Lee

Patent number: 7176806Abstract: The invention provides a system and battery including a state-of-charge indicator (SOCI) to monitor and display the amount of charge within the battery. The SOCI is capable of operating in a hibernate mode, an active mode, and/or a sleep mode. The battery may be manufactured, shipped and/or stored with the SOCI operating in a power-saving hibernate mode. The SOCI may exit the hibernate mode and begin operating in active mode if a physical key connected to the battery is removed. In addition, the SOCI may operate in a sleep mode while the battery is not being used to conserve power. Furthermore, the invention provides a method of making a battery including a SOCI to monitor and display the state of charge of the battery.Type: GrantFiled: February 23, 2005Date of Patent: February 13, 2007Assignee: Eaglepicher Energy Products CorporationInventors: Gregg C.

Patent number: 7123155Abstract: A method and an electronic device monitor a battery of the device with respect to device operational mode in one or both of battery charge level monitoring and battery cut-off determination. Mode-based monitoring employs a mode-specific wait period prior to performing a measurement used to determine a remaining charge level of a battery. The mode-specific wait period depends on the operational mode immediately preceding the measurement and therefore, accounts for battery recovery effects on measurement accuracy. Mode-based cut-off determination employs information regarding an impending operational mode to determine whether or not a remaining charge level of the battery is sufficient to support the mode. Only those operational modes for which there is sufficient remaining charge are enabled while operational modes for which there is insufficient remaining power are disabled.Type: GrantFiled: April 5, 2002Date of Patent: October 17, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventor: Charles E.

Patent number: 7023353Abstract: A warning device including a status and function indicator circuit for indicating the status and function of the warning device. In a visual warning device such as a strobe light, the status and function indicator circuit includes a status output device such as an LED. The LED and associated circuitry are configured to indicate both proper operation of the visual warning device and, in the event of a device failure, will indicate whether the fault lies with circuitry for the visual warning device or simply with a warning output device.Type: GrantFiled: April 7, 2004Date of Patent: April 4, 2006Assignee: Electronic Controls CompanyInventors: Tony J.
