Patent number: 11960464Abstract: A materialization configuration request is received via a programmatic interface from a client of a journal-based multi-data-store database. The request indicates a partitioning rule to be used to select, for respective writes indicated in committed transaction entries of a journal, the materialization node at which the writes are to be stored. A control plane component of the database verifies that a set of materialization nodes corresponding to the partitioning rule has been established, and initiates the propagation of writes from the journal to the materialization nodes by respective write appliers.Type: GrantFiled: July 23, 2018Date of Patent: April 16, 2024Assignee: Amazon Technologies, Inc.Inventors: Timothy Daniel Cole, John Michael Morkel, Tate Andrew Certain, Christopher Richard Jacques de Kadt, Artem Danilov, Andrew Wayne Ross, Allan Henry Vermeulen

Patent number: 11621547Abstract: An electronic component holder for a control box for holding non-passive components, such as capacitors, relays and circuit breaker switches to a surface of the control box. The electronic component holder is welded or secured to an inner surface of the control box. By the structure of the electronic component holder, the need for use of conventional fasteners, such as screws or bolts, to hold the electronic components in place within the control box is eliminated.Type: GrantFiled: January 23, 2020Date of Patent: April 4, 2023Assignee: Tulsar Canada LtdInventors: George Micevski, Jim Streeter, Mike Colalillo, Michael Certain, Joe Bonnici

Patent number: 10762189Abstract: A system and method to support authentication or device pairing. A respective indication is received from a respective output of each respective contact element within a plurality of contact elements. The respective output indicates a touching of the respective contact element. Based on receiving the respective indication, a respective state associated with the respective contact element is changed. The respective contact element is controlled to change its respective visual state to correspond to its respective state. Based on receipt of the respective indication, it is determined whether the respective states of the plurality of contact elements match a determined pattern. Based on a determination that the respective states of the plurality of contact elements match the determined pattern, access to an operation is authorized.Type: GrantFiled: June 22, 2015Date of Patent: September 1, 2020Assignee: BlackBerry LimitedInventors: John William Wynen, Michael Certain

Patent number: 7873339Abstract: A test method is for determining total isotropic sensitivity (TIS) of a mobile wireless communications device using an RF source controllable to a plurality of source values having a relatively small uncertainty associated therewith. The mobile wireless communications device may includes an antenna and a RF receiver coupled to the antenna and outputting an RSSI value having a relatively large uncertainty associated therewith. The method may include measuring a sensitivity of the RF receiver, and measuring an antenna gain pattern for the antenna based upon controlling the RF source to respective source values causing the RE receiver to generate a same target RSSI value as the RF source and wireless communications device are angularly moved relative to one another to thereby reduce the relatively large uncertainty of the RSSI value. The TIS may be determined based upon the measured sensitivity of the RF receiver and the measured antenna gain pattern.Type: GrantFiled: January 31, 2008Date of Patent: January 18, 2011Assignee: Research In Motion LimitedInventors: Yihong Qi, Michael Certain, Qingmai Zhou, Perry Jarmuszewski

Patent number: 7555295Abstract: A test method is described for determining radiated radio frequency (RF) receiver sensitivity may include determining a bit error rate (BER) versus traffic channel (TCH) power level function for an initial channel, determining an estimated TCH power level for a subsequent channel based upon the BER versus TCH power level function and a desired BER, and measuring a BER of a subsequent channel based upon the estimated TCH power level. The method may further include comparing the measured BER to the desired BER and using a difference therebetween along with the BER versus TCH power level function to determine a next estimated TCH power level, and repeating measuring and comparing if the difference is greater than a threshold to thereby determine a TCH power level in the subsequent channel corresponding to the desired BER.Type: GrantFiled: March 1, 2006Date of Patent: June 30, 2009Assignee: Research In Motion LimitedInventors: Yihong Qi, Perry Jarmuszewski, Michael Certain

Patent number: 7489905Abstract: A test method is for determining RF path loss between an RF source and an RF receiver. The RF source may transmit RF power values at a relatively fine granularity, and the RF receiver may generate RSSI values at a relatively coarse granularity and have an unknown hysteresis about each transition between adjacent RSSI values. Hysteresis edges may be determined about a given RSSI value transition at the RF receiver by sweeping RF power values transmitted from the RF source in increasing and decreasing directions. A relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values may be determined using the hysteresis transition edges. The RF path loss for a given channel may be determined based upon a given RSSI at a given RF power value and the relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values.Type: GrantFiled: March 1, 2006Date of Patent: February 10, 2009Assignee: Research In Motion LimitedInventors: Yihong Qi, Perry Jarmuszewski, Michael Certain
