Publication number: 20160246975Abstract: A multi-functional device is attached to a secure network and includes a control circuit. The control circuit receives indications as to whether a user is authenticated to use the multi-functional device and in response, generates and sends a control signal to the multi-functional device. As long as the multi-functional device continues to receive the control signal, the multi-functional device remains in an operational mode to allow the authenticated user to access the multi-functional device functions. If the multi-functional device ceases to receive the control signal, the multi-functional device deactivates itself.Type: ApplicationFiled: May 2, 2016Publication date: August 25, 2016Inventor: Dennis Keith Allison

Patent number: 9264077Abstract: A mobile communications device may include an RF signal source configured to generate RF signals over an RF frequency band(s), and an RF transmitter coupled to the RF signal source. The RF transmitter may include an RF amplifier configured to operate over a plurality of different power control levels. The RF amplifier may have an input configured to receive the RF signals from the RF signal source and an output having an impedance which changes based upon changes between the different power control levels. The RF transmitter may further include a shunt resistor(s) coupling the output of the amplifier to a voltage reference, and the shunt resistor(s) may be configured to decrease a highest impedance change of the RF amplifier output to below a threshold impedance level. An antenna(s) may be coupled to the output of the RF amplifier to operate over the at least one RF frequency band.Type: GrantFiled: May 31, 2012Date of Patent: February 16, 2016Assignee: BLACKBERRY LIMITEDInventors: Dennis Keith Shaw, Prasad Venkatesh Madabusi Srinivasan
