Patent number: 9552048Abstract: A pull-up resistor of an electronic device pulls up a potential of a USB signal line that is for connection with a host, thereby allowing the host to detect a communication speed. In response to a status request from the host in a normal power mode, a transmission-reception section transmits a status response indicating a switchable status when the electronic device is switchable to a power saving mode. A control section performs switching to the power saving mode after the host suspends transmission of the status request upon receipt of the status response, and performs switching to the normal power mode in response to a specific event within the electronic device in the power saving mode. A switch disables the pull-up to inform the host about disconnection, and enables the pull-up to inform the host that the connection is re-established, thereby causing transmission of the status request to be resumed.Type: GrantFiled: May 22, 2015Date of Patent: January 24, 2017Assignee: KYOCERA Document Solutions Inc.Inventor: Yuya Maesono

Patent number: 9552049Abstract: An activation signal is provided in response to a user gripping force incident to a grip switch. Electronic circuitry transitions from an inactive state to an active state in response to the activation signal. The activation signal may also include encoded information regarding user identity, gripping force magnitude, user input gesturing, and the like. The electronic circuitry may use the information encoded in the signal to select or perform particular functions or operations. Power consumption of a stylus, user device, or other apparatus is reduced, or various functions are improved, accordingly.Type: GrantFiled: September 25, 2013Date of Patent: January 24, 2017Assignee: Amazon Technologies, Inc.Inventors: David George Butler, Richard William Mincher

Patent number: 9552050Abstract: An information processing device having plural control units appropriately executes an arbitration process when a control unit is hibernating (in power-saving mode) and transmits data correctly to an external device. The information processing device has a first CPU and a second CPU; a first memory embedded in a semiconductor chip including the first CPU and second CPU; and a second memory disposed externally to the semiconductor chip. The first CPU executes an arbitration process according to the type of event that occurred when the first CPU is in a first state, the second CPU and the second memory are in a second state different from the first state, and an event requiring sending data from the first memory to the second memory occurs.Type: GrantFiled: May 22, 2015Date of Patent: January 24, 2017Assignee: Seiko Epson CorporationInventors: Masayo Miyasaka, Youji Tsuchiya

Patent number: 9552053Abstract: A system and method are provided for strategic power supply sequencing in a computer system. The system and method includes a plurality of processing resources that process data and a plurality of power supplies that provide power for the processing resources. A power management engine adjusts the power supplies in response to processing resource changes to optimize power consumption. The power management engine brings online power supplies to meet the demand created by bringing online additional processing resources and brings offline power supplies to meet the decreased demand caused by a decrease in the number of processing resources. Also, the power management engine rotates which power supplies operate to take advantage of more efficient power supplies and to extend the lives of the power supplies. The power management engine also adjusts the power supplies in advance based upon predicted demand levels for the computer system.Type: GrantFiled: November 30, 2007Date of Patent: January 24, 2017Assignee: DELL PRODUCTS L.P.Inventors: Clint H. O'Connor, Alfred C. Hartmann, Keith R. Abell
