Patent number: 10911366Abstract: Technologies for balancing throughput across input ports include a network switch. The network switch is to generate, for an arbiter unit in a first stage of a hierarchy of stages of arbiter units, turn data indicative of a set of turns in which to transfer packet data from devices connected to input ports of the arbiter unit. The network switch is also to transfer, with the arbiter unit, the packet data from the devices in the set of turns. Additionally, the network switch is to determine weight data indicative of the number of turns represented in the set and provide the weight data from the arbiter unit in the first stage to another arbiter unit in a subsequent stage to cause the arbiter unit in the subsequent stage to allocate a number of turns for the transfer of the packet data from the arbiter unit in the first stage.Type: GrantFiled: June 30, 2017Date of Patent: February 2, 2021Assignee: Intel CorporationInventors: Scott S.

Patent number: 8625270Abstract: A pen-type computer peripheral device includes an elongated housing containing a PCBA having a plug connector, and cap/cover that is slidably connected to a front portion of the housing. Locking structures are respectively integrally molded onto opposing surfaces of the housing and cap/cover that cooperate to prevent separation of the cap/cover from the housing. By manually pushing (sliding) the cap/cover relative to the housing, the plug connector is effectively moved between a retracted position, in which the plug connector is disposed inside the cap/cover, and a deployed position in which the plug connector extends through a front housing opening of the cap/cover such that the plug connector is operably exposed for insertion into a host system.Type: GrantFiled: October 6, 2011Date of Patent: January 7, 2014Assignee: Super Talent Technology, Corp.Inventors: Jim Chin-Nan Ni, Abraham C.
