Patent number: 11019640Abstract: An apparatus has a first communication module that is compatible with a first wireless communication technology, and a second communication module that is compatible with a second, different, wireless communication technology. Transmissions by each communication module may contribute to interference at the other communication module. In one example, a Block Acknowledgement Request is transmitted by the apparatus during a downlink period of the second communication module so that the Block Acknowledgement transmitted in response is received during the downlink period. In another example, the apparatus calculates a maximum size of A-MPDU to receive and notifies an access point of that maximum size. In a further example, the apparatus, having notified an access point of operation in a power save mode, polls the access point for buffered frames at the start of a downlink period of the second communication module.Type: GrantFiled: April 1, 2019Date of Patent: May 25, 2021Assignee: BlackBerry LimitedInventors: Mohammed Nawaf Smadi, Goran Hageltorn, Ghada Badawy

Publication number: 20190200489Abstract: A cooling unit having a liquid coolant flow through the cooling unit and a gas coolant flow through the cooling unit is controlled using a temperature signal representing a present temperature associated with equipment cooled by the cooling unit and a delayed-effect variable signal representing a variable having a potentially delayed impact on the temperature associated with the equipment cooled by the cooling unit. A thermal system model to which the temperature signal, the delayed-effect variable signal, the liquid coolant flow and the gas coolant flow are inputs is used to calculate a projected future temperature associated with the equipment. Responsive to the projected future temperature, coolant flow is adjusted to target the projected future temperature toward a set-point by adjusting the liquid coolant flow and the gas coolant flow. The delayed-effect variable signal may represent, for example, a processing workload or a current drawn by the equipment.Type: ApplicationFiled: December 21, 2018Publication date: June 27, 2019Inventors: Fernando Martinez Garcia, Ghada Badawy, Douglas Graham Down

Patent number: 10051441Abstract: A device in a peer-to-peer (P2P) group has the role of group owner. A different device in the P2P group may take on the role of group owner without ending the P2P group and create a new P2P group. Multiple P2P groups may be merged into a single P2P group. A single P2P group may be split into multiple independent P2P groups, each with its own group owner. A group owner of a P2P group may notify the client devices in the P2P group that it is about to leave the P2P group. A client device in a P2P group may be appointed in a new role of backup group owner, to take on the role of group owner in the event of a departure of the group owner, thereby providing continuity. Techniques for maintaining upper layer continuity through changes in topology of P2P groups are disclosed.Type: GrantFiled: December 22, 2016Date of Patent: August 14, 2018Assignee: BlackBerry LimitedInventors: Mohammed Nawaf Smadi, Vytautas Robertas Kezys, Ghada Badawy, James Randolph Winter Lepp, Michael Peter Montemurro, Stephen McCann, David Philip Hole

Patent number: 9654999Abstract: These teachings provide for transmitting to a wireless access point a sleep status indicator for a wireless transceiver. These teachings then provide for delaying having that wireless transceiver enter a sleep mode of operation until at least a predetermined period of time following transmission of the wireless transceiver sleep status indicator. These teachings also provide for determining a need to slow down a rate of receiving data from the wireless access point via the wireless transceiver. In this case the aforementioned sleep status indicator is transmitted in response to determining that need to slow down the rate of receiving data from the wireless access point.Type: GrantFiled: June 20, 2014Date of Patent: May 16, 2017Assignee: BlackBerry LimitedInventors: Mohammed Nawaf Smadi, Vytautas Robertas Kezys, Ghada Badawy
