Publication number: 20110143809Abstract: A mobile wireless communications device includes a user-visible peripheral, such as a display, and a processor. A reset management block is associated with the processor to manage reset of the device. The processor includes the use of an operating system (OS) which is resettable along with a reset of a state of the user-visible peripheral. The operating system is also resettable without resetting the state of the user-visible peripheral to avoid a user-visible change therein.Type: ApplicationFiled: October 19, 2010Publication date: June 16, 2011Applicant: Research In Motion LimitedInventors: Leonardo José Silva SALOMONE, Jerry E.

Patent number: 7848271Abstract: The invention relates to a system and a method for selectively reducing power consumption of a communication device communicating with a network. In the method, it comprises the following steps: de-activating at least one communication subsystem of the device during intervals when the device is placed in a power save mode; and while the device is in the power save mode the method re-activates the subsystem in two instances. For the first instance, the communication subsystem is re-activated in relation to a first connection condition, and is then de-activated after a first event. For the second instance, the subsystem is re-activated in relation to a second connection condition and is then de-activated after a second event.Type: GrantFiled: June 26, 2007Date of Patent: December 7, 2010Assignee: Research In Motion LimitedInventors: Leonardo Jose Silva Salomone, Michael Peter Montemurro

Publication number: 20100157864Abstract: One illustrative method for reducing power consumption in a mobile communication device of a wireless local area network (WLAN) involves the steps of identifying a communication signal quality value between the mobile device and a wireless access point of the WLAN with which the mobile device is currently associated; determining an initial timer value based on a predefined relationship with the communication signal quality value where, as the communication signal quality value decreases, the initial timer value correspondingly decreases; initializing a scan trigger timer with the initial timer value and running the scarf trigger timer; and upon expiration of the scan trigger timer: causing a scanning operation to be performed for identifying one or more wireless access points in a coverage region; and repeating the acts of identifying, determining, initializing and running the scan trigger timer, and causing the scanning operation to be performed.Type: ApplicationFiled: December 23, 2008Publication date: June 24, 2010Applicant: RESEARCH IN MOTION LIMITEDInventors: Leonardo Jose Silva Salomone, Sherif Abdel-Kader

Publication number: 20090279492Abstract: A mobile communication device identifies and selects a wireless local area network (WLAN) available for communications in its coverage area. Automatically, without detecting any requests made by a user via a browser application. The mobile device initiates a request (e.g. an HTTP GET request) to a predetermined server site of a communication network which is outside of the WLAN. In response to initiating the request, the mobile device receives a response message via the WLAN and identifies, from the response message, whether the request to the predetermined server site has been redirected to a redirect server site. The WLAN may be a WLAN “hotspot,” where the redirect server site is a login server. The identifying may be performed by comparing content from the response message to predetermined content of the predetermined server site. In response to identifying that the request has been redirected, the mobile device causes an indication to be produced at its user interface.Type: ApplicationFiled: February 20, 2009Publication date: November 12, 2009Applicant: RESEARCH IN MOTION LIMITEDInventors: Michael Peter Montemurro, Alain Rene Gagne, Denis Fedotenko, Michael Knowles, Kevin Oerton, Liam Ronald Quinn, Leonardo Jose Silva Salomone

Patent number: 7046046Abstract: A signal scaling circuit for accurately reducing the effective amplitude of an input signal by a rational factor N/M, where N and M are integers and N<M, is disclosed. An input, reference, bias and output node as well as control circuitry are selectively coupled to M switched capacitor circuits such that N/M scaling may be achieved. Cooperation between the M switched capacitor circuits and the control circuitry divides the M switched capacitors circuits into subsets of N and M?N switched capacitors, respectively. Each subset is then selectively coupled to an input, reference and/or bias signal to produce an output signal having as one of its components an N/M portion of the input signal. Error reduction in the scaled signal is achieved by shuffling the switched capacitor circuits populating each subset after selected time intervals.Type: GrantFiled: March 23, 2004Date of Patent: May 16, 2006Assignee: Microchip Technology IncorporatedInventors: Gabor C.

Patent number: 5702262Abstract: An insulating member has two (2) spring arms each normally biased to a first position and each pivotable to a second position. A pin in a housing at one end of the spring arms provides the spring arm pivot fulcrum. Resilient electrical conductors extend through apertures in the other ends of the spring arms. Looped portions in the conductors at positions beyond the apertures resiliently engage, respectively, probes and shield casings in a pair of electrical connectors when the spring arms are biased to the first positions. Additional looped portions in the conductors at positions between the apertures may be fixedly positioned relative to the housing by an insulating pin extending into the housing to the approximate center of such additional looped portions. The probes and shield casings are included in coaxial connectors disposed within the housing. The connectors include insulators between the probes and the shield casings. The connectors are coaxial with a pair of barrels disposed within the housing.Type: GrantFiled: October 4, 1996Date of Patent: December 30, 1997Assignee: Trompeter Electronics, Inc.Inventors: Gregory S. Brown, Frank Quach, Jose Silva

Patent number: 5382173Abstract: A member has two (2) spring arms each movable between first and second positions. Each spring arm is normally biased to a first position and is movable to a second position. Each spring arm has at its free end an insulator and a conductor disposed on the insulator. The insulator isolates the conductor electrically from the associated spring arm. An electrical lead is connected between the conductors. In the first position of the spring arms, the electrical conductors engage individual ones of a pair of probes and establish common probe potentials. Each probe is disposed coaxially in an insulator in an individual one of a pair of electrical connectors and the insulator is disposed coaxially in a casing in the connector. The probe extends axially beyond the insulator and the casing in each connector so that the associated electrical conductor is able to engage the probe in that connector in the first position of the spring arm.Type: GrantFiled: September 1, 1993Date of Patent: January 17, 1995Assignee: Trompeter Electronics, Inc.Inventors: Gregory S. Brown, Frank Quach, Jose Silva

Patent number: 5280254Abstract: A connector assembly includes first and second conductive probes, first and second conductive shields respectively enveloping the first and second probes in an insulated relationship and a cover insulatingly enveloping the shields. First and second barrels may be disposed within the cover at a first axial end of the cover. Third and fourth barrels may be disposed within the cover, at the opposite axial end of the cover in enveloping relationship to respective ones of the shields. An assembly including an impedance is insulatingly supported by the third and fourth barrels. An actuator assembly insulatingly supported by the first and second barrels has (a) a first operative relationship establishing electrical continuity between the probes and between the shields and (b) a second operative relationship interrupting such continuities and establishing a circuit including an individual one of the probes, the impedance and the corresponding one of the shields.Type: GrantFiled: March 16, 1992Date of Patent: January 18, 1994Assignee: Trompeter Electronics, Inc.Inventors: Tracy A.
