Patent number: 11381802Abstract: Customer wide angle lenses and methods and apparatus for using such lenses in individual cameras as well as pairs of cameras intended for stereoscopic image capture are described. The lenses are used in combination with sensors to capture different portions of an environment at different resolutions. In some embodiments ground is capture at a lower resolution than sky which is captured at a lower resolution than a horizontal area of interest. Various asymmetries in lenses and/or lens and sensor placement are described which are particularly well suited for stereoscopic camera pairs where the proximity of one camera to the adjacent camera may interfere with the field of view of the cameras.Type: GrantFiled: June 30, 2020Date of Patent: July 5, 2022Assignee: Nevermind Capital LLCInventors: David Cole, Alan McKay Moss, Michael P.

Publication number: 20110002062Abstract: A sample and hold circuit is disclosed that provides longer hold times. An analog multiplexer circuit is also disclosed that exhibits low switch leakage. The analog multiplexer circuit comprises a shared node, a plurality of input circuits, a control input for selecting one or more of the plurality of input circuits, and an amplifier coupled to the shared node. Each input circuit comprises an input node, a primary input switch for selectively coupling an input to the input node, and a secondary input switch for selectively coupling the input node to the shared node, wherein the secondary input switch comprises one or more transistor switches. The parasitic drain and source diodes of one or more transistor switches in secondary input switch in a selected input circuit are coupled to a voltage that is distinct from an input signal of the selected input circuit.Type: ApplicationFiled: July 1, 2010Publication date: January 6, 2011Applicant: AGERE SYSTEMS INC.Inventors: Jonathan H.

Patent number: 7773332Abstract: A sample and hold circuit is disclosed that provides longer hold times. The sample and hold circuit can be used in a disc drive to provide improved read-to-write and write-to-read mode transitions. The sample and hold circuit has an input and an output, and includes at least one capacitive element for retaining a charge. The capacitive element is connected to a node between the input and the output. The sample and hold circuit includes at least one input switch to selectively connect the capacitive element to the input and at least one output switch to selectively connect the capacitive element to the output. In addition, an amplifier is connected to the node and has an offset voltage. In this manner, a voltage drop across at least one of the input and output switches is limited to the offset voltage.Type: GrantFiled: November 21, 2003Date of Patent: August 10, 2010Assignee: Agere Systems Inc.Inventors: Jonathan H.

Patent number: 7724460Abstract: A recording system employing a magneto-resistive (MR) element senses a resistance value of the MR element and generates one or more MR resistance (MRR) signal values based on the sensed MR element resistance value. The MRR signal values might be, for example, current or voltage values proportional or inversely proportional to the MR element resistance value. The MRR signal values might be employed to control one or more of: i) a unity gain bandwidth of a bias loop for the MR element, ii) an MR read head preamplifier low corner frequency, and iii) a slew rate across the MR element.Type: GrantFiled: January 13, 2005Date of Patent: May 25, 2010Assignee: Agere Systems Inc.Inventors: David J. Fitzgerald, Jeffrey A. Gleason, James P. Howley, Scott M. O'Brien, Michael P. Straub

Patent number: 7630159Abstract: An apparatus and method for determining a resistance of a magneto-resistive head. A current drawn by the head, in response to a fixed bias voltage across the head, is converted to a zero temperature coefficient current such that when supplied to a resistor connected to an input terminal of a comparator the effects of variations in the resistance value are avoided. An output signal of the comparator indicates the resistance of the magneto-resistive head.Type: GrantFiled: May 27, 2005Date of Patent: December 8, 2009Assignee: Agere Systems Inc.Inventors: Scott M. O'Brien, Michael P. Straub, Jeffrey A. Gleason, Shubha Bommalingaiahnapallya, Nameeta Krenz, Arvind Aemireddy

Patent number: 7194079Abstract: Improved call forwarding methods and apparatus are described. Dialing of multiple call forwarding locations in parallel is supported. Distinguishing between fax and voice calls and using different forwarding numbers for each type of call is also supported. Forwarding of facsimiles by E-mail as an alternative or in addition to forwarding by phone is also supported. Call forwarding security features such as requiring an answering party to enter a PIN before being connected to the calling party are also described. The call forwarding services can be implemented in the PSTN using AIN techniques avoiding the need to purchase or upgrade customer premise equipment to receive the call forwarding service. Alternatively, the call forwarding methods may be implemented using customer premise equipment such as a PBX.Type: GrantFiled: April 24, 2001Date of Patent: March 20, 2007Assignee: Verizon Services Corp.Inventors: Michael P.

Patent number: 7119977Abstract: User data is read from a medium having servo data and user data encoded thereon. The user data is read with a read/write head that is operable in a write mode and a read mode. Servo data is read in a time window following a transition from write mode to read mode, with a frequency passband that has a first low frequency corner. User data is read from the medium after expiration of the time window, with a frequency passband that has a second low frequency corner that is lower than the first low frequency corner.Type: GrantFiled: March 28, 2005Date of Patent: October 10, 2006Assignee: Agere Systems Inc.Inventors: Daniel J.

Patent number: 6895324Abstract: Methods and apparatus for storing, accessing, generating and using information about speed limits and speed traps are described. The system includes a positional sensor such as a GPS device. Position information is used to access a database of speed limit and/or speed trap information. The database may be local or remote. Access to a remote database may be achieved using a wireless communications device such as a wireless (cellular) modem. Encountered speed traps are logged in response to the activation of a speed trap alert button by a user of the device or the output of a radar/laser detector. Speed trap position, date and time information is transmitted to the remote database system. Speed limit information is used to control the speed of the automobile as part of a cruise control operation and/or is used to provide the motor vehicle operator with warnings, e.g., that the applicable speed limit is being exceeded.Type: GrantFiled: October 23, 2003Date of Patent: May 17, 2005Inventor: Michael P.

Patent number: 6650182Abstract: A non-linear transconductance amplifier includes a differential input stage and a non-linear transconductance stage operatively coupled to the differential input stage. The differential input stage includes first and second inputs forming a non-inverting input and an inverting input, respectively, of the amplifier for receiving an input differential signal. The non-linear transconductance stage generates an output of the amplifier having a linear transconductance that is substantially zero when the input differential signal is within a predetermined range and a non-linear large transconductance when the input differential signal is outside the predetermined range. The amplifier provides improved response time to widely varying load conditions while possessing a low loop bandwidth. A threshold region where the output of the amplifier is substantially zero can be operatively adjusted and tightly controlled.Type: GrantFiled: December 14, 2001Date of Patent: November 18, 2003Assignee: Agere Systems Inc.Inventors: Jong K.
