Patent number: 7221355Abstract: A portable transmitter having no power consumption while inactive, and a nearly simultaneous indicator of the cause of a transition when power is provided. A transmitter pen in a locator system, having more than one sensor, each separately triggerable, and indicating which sensor was triggered. An on-off circuit coupled to a 1.5 volt battery power source, to a power regulator and multiple sensors, so the regulator consumes no power while inactive. The on-off circuit consumes no power while inactive. When one of the sensors is triggered, the on-off circuit activates, while indicating which sensor was triggered. The circuit has an ON state, in which the regulator and operational circuits operate normally, an IDLE state, in which the circuit consumes little power in anticipation of being activated, and a SHUT-DOWN state, in which the circuit consumes little power in anticipation of a sensor being released.Type: GrantFiled: December 31, 2003Date of Patent: May 22, 2007Assignee: Luidia Inc.Inventor: Yao Ding

Patent number: 7193641Abstract: A method of exposing imaging data onto a sensitized medium including exposing K sets of N of tracks on to the medium according to a corresponding part of imaging data, each successive set being a pixel distance apart in a fast scan direction. The method further includes exposing L sets of N tracks onto the medium with an offset of M pixels in a slow scan direction substantially perpendicular to the fast scan direction, according to a second corresponding part of imaging data. The method includes repeating alternately exposing K sets and L sets of N tracks until the complete medium is exposed along the fast scan direction. During or after the alternately exposing K sets and L sets, there is progression in the slow scan direction such that after exposing the complete length of N tracks of exposed pixels, the next N tracks match along the medium at the start of the next N tracks.Type: GrantFiled: December 22, 2004Date of Patent: March 20, 2007Assignee: Esko-Graphics A/SInventors: Thomas Klein, Wolfgang Sievers

Patent number: 7151945Abstract: A method and apparatus for synchronizing a local clock value in a wireless receiver receiving a data unit containing synchronization information. The method includes receiving a first data unit containing synchronization information, extracting the synchronization information from the received first data unit, copying a local free-running clock at a known reference point in time relative to the time the first data unit was received to generate a local timestamp; and calculating an offset to the free-running clock using the extracted synchronization information and the local timestamp, the calculating in non real-time, such that the sum of the calculated offset and the value of the free-running clock provides a local clock value that is approximately synchronized in time. The apparatus implementing the method is part of a node of a wireless station, and provides a time synchronization function, typically at the MAC layer.Type: GrantFiled: March 29, 2002Date of Patent: December 19, 2006Assignee: Cisco Systems Wireless Networking (Australia) Pty LimitedInventors: Andrew F.

Patent number: 6940843Abstract: An apparatus for inclusion and a method for operation in a station (STA) of a wireless network. The method includes received data from at least one remote station and determining a measure of the signal quality, e.g., a measure of the EVM from samples of the data received from the remote station(s). If the remote station(s) is/are access point(s), the station selects an access point for association according to criteria that include the measure of the EVM from the remote station. If the received data includes a request management message, the station responds to the request management message with a response management message that include a measure of the EVM of the received data corresponding to the request management message. Thus, the remote station receiving the response management message receives an indication of the quality of the link between the station and the remote station without the receiving remote station necessarily being EVM-capable.Type: GrantFiled: November 3, 2003Date of Patent: September 6, 2005Assignee: Cisco Technology, Inc.Inventors: David S.

Patent number: 6744324Abstract: A frequency synthesizer, a calibrator thereof, and an operating controller thereof are described. The synthesizer comprises a main charge pump that drives a voltage controlled oscillator (VCO) through a loop filter. The calibrator includes a second, replica charge pump that can also drive the VCO, but is set up to output only its maximum or minimum analog output control voltage. Since the construction and characteristics of the replica charge pump duplicate the main charge pump, the main charge pump's minimum and maximum analog control outputs can be cloned out to the VCO on demand. A VCO calibration procedure therefore includes switching the VCO to each of its ranges set by a bank of fixed capacitors, and using the replica charge pump to drive the VCO to its minimum and maximum frequency for each range setting.Type: GrantFiled: April 14, 2003Date of Patent: June 1, 2004Assignee: Cisco Technology, Inc.Inventors: Andrew R. Adams, Neil H. Weste, Stephen C. Avery

Patent number: 6731270Abstract: A piezoelectric transducer is provided, in which a piezoelectric shell has conductive layers on the outside and inside of the shell, which are adapted to be connected to a signal input source. When the conductive layers are activated, the piezoelectric layer resonates to produce an output signal waveform from the shell structure. An alternative embodiment includes a flat piezoelectric layer with opposing conductive layers, which is then formed into a shell structure. In preferred embodiments, an inner spool is located within the shell structure, which acts to increase the output sound pressure level for the transducer. To increase the sound pressure level further, the inner spool preferably includes a recessed area, which defines a void between the inner conductive layer on the shell and the recessed area. The void acts to increase the characteristic output sound pressure level for the transducer.Type: GrantFiled: October 21, 1998Date of Patent: May 4, 2004Assignee: Luidia Inc.Inventor: Carol A. Tosaya
