Patent number: 9703362Abstract: An electronic device includes a power supply unit, a to-be-used function setting unit, and a function-specific power supply control unit. The power supply unit supplies electric power to a constituent unit of the electronic device from a main power source. The to-be-used function setting unit sets functions to be used when the main power source is turned on. The function-specific power supply control unit controls the power supply unit to a) supply electric power to a constituent unit corresponding to a function that has been set by the to-be-used function setting unit when the main power source is turned on and b) supply electric power to a constituent unit corresponding to a function that has not been set by the to-be-used function setting unit when the function that has not been set is selected after turning on the main power source.Type: GrantFiled: November 25, 2014Date of Patent: July 11, 2017Assignee: KYOCERA Document Solutions Inc.Inventors: Katsuji Furushige, Masaya Okuda, Masato Hirota

Patent number: 9632795Abstract: An electronic device including a control unit, an embedded controller and a battery module is provided. During a booting procedure of the electronic device, the embedded controller reads a reported battery capacity and a battery temperature of the battery module. The embedded controller determines whether the reported battery capacity is lower than a minimum capacity, and further determines whether the battery temperature is lower than a minimum temperature when the reported battery capacity is lower than the minimum capacity. When the reported capacity is lower than the minimum capacity and the battery temperature is also lower than the minimum temperature, the embedded controller generates a fake battery capacity, according to which an operating system of the electronic device performs various operations. In this application, the battery module of the electronic device remains working even when the electronic device is in a low-temperature and low-battery activation environment.Type: GrantFiled: November 28, 2014Date of Patent: April 25, 2017Assignee: Getac Technology CorporationInventor: Chun-Chi Wang

Patent number: 9537665Abstract: To address the need for power management, the following facilitates maintaining power states in an efficient manner based at least in part on managing packets at different layers of an input/output interface that supports multiple layers. One specific example prevents a destructive event for link layer control logic because packets and information might have been lost or dropped due to a hang condition and/or a dropped packet. In yet another example of power management, this facilitates a low power platform state by preventing the loss of packets or data upon exiting a platform power state upon initiation of a link reset condition by preventing certain types of packets from reaching link layer controller logic.Type: GrantFiled: August 20, 2013Date of Patent: January 3, 2017Assignee: Intel CorporationInventors: Selim Bilgin, Lily P.

Patent number: 9529405Abstract: A system and method for managing idleness of functional units in an IC is disclosed. An IC includes a subsystem having a number of functional units and an idle aggregation unit. When a particular functional unit determines that it is idle, it may assert an idle indication to the idle aggregation unit. When the respective idle indications are concurrently asserted for all of the functional units, the idle aggregation unit may assert and provide respective idle request signals to each of the functional units. Responsive to receiving an idle request unit, a given functional unit may provide an acknowledgement signal to the idle aggregation unit if no transactions are incoming. If all functional units have concurrently asserted their respective acknowledgement signals, the idle aggregation unit may provide an indication of the same to a clock gating unit, which may then gate the clock signal(s) received by the functional units.Type: GrantFiled: August 14, 2014Date of Patent: December 27, 2016Assignee: Apple Inc.Inventors: Erik P.
