  • Patent number: 9733288
    Abstract: The resonant frequency of a reactive circuit is determined in situ by determining phase angle differences between an A.C. driving voltage applied to a transformer primary winding and an induced alternating current in the transformer secondary winding. The phase angle is determined indirectly by detecting when the driving voltage applied to the primary changes its polarity and when an induced current in the secondary changes its polarity. The time difference between those polarity changes indicates whether the voltage leads or lags the current or is in phase. A driving voltage frequency is adjusted in real time until the phase angle differences disappear. A duty cycle of the driving signal applied to the primary is also adjusted to change the voltage induced in the secondary winding. The duty cycle is adjusted by changing either a phase of primary driving voltages or the duty cycle of primary driving voltages.

  • Patent number: 9021062
    Abstract: A communication is established between a client device and a server device, where the server device executes one or more hosted virtual desktop (HVD) applications for the client device. A media data stream including at least one of audio content and video content is transmitted from the client device to the server device, where audio and video content of the media data stream is captured by one or more input devices at the client device and is utilized by an HVD application at the server device. In response to a request for the media data stream by a second application that is local to the client device or is operating at a remote device, transmission of the media data stream to the server device is selectively suspended or shared with the second application.

  • Patent number: 8966093
    Abstract: A host device receives from a user at a first client device a first login request for hosted virtual desktop (HVD) services. A first virtual desktop infrastructure (VDI) session is started upon receiving a valid first login request. A first unified communications (UC) session is established between the first client device and an endpoint device. A second login request is received from the user at a second client device, the second login request configured to request HVD services. A second VDI session is started to mediate an HVD session for the user upon receiving a valid second login request. A second UC session is established between the second client device and the endpoint device. A media communication session associated with the first UC session is transferred from the first client device to the second client device after the second VDI session is started and the second UC session is established.

  • Patent number: 8624570
    Abstract: Methods and systems for power conversion are disclosed, including receiving at least one interrupt indicative of a transient power condition of the power converter and switching the processor to operate in a second mode from a first mode responsive to the interrupt. The switching enables the processor to allocate greater resources to process a power output parameter of the power converter operating in the transient power condition compared to resources allocated by the processor operating in the first mode to process the power output parameter.

  • Patent number: 8569907
    Abstract: Disclosed herein is an electrical system topology for voltage regulation in a 12-volt vehicle power distribution system. Particularly, a single transistor power converter is configured to operate in both as a traditional voltage regulator mode (i.e., as buck converter to reduce the field voltage applied to an alternator to a value less than that available from the main bus) and as an alternator field current boost converter (i.e., as a boost converter to boost the field voltage applied to an alternator to a value greater than that available from the main bus). The converter may also include a controller that incorporates a thermal model of the alternator to limit the amount of voltage boost applied and/or direct temperature measurement of the alternator or alternator components. Additionally, these two approaches may be combined such that measured temperatures are used to refine the temperature estimated by the thermal estimator.

  • Patent number: 8466646
    Abstract: The position of a rotor of a motor is determined. The motor includes a stator having a plurality of coils. The rotor includes at least one rotating magnetic field device. When the rotor is moving below a threshold speed, the current in the coils is measured. A pre-programmed data structure is accessed. The data structure stores stator currents associated with predetermined rotor positions. A first absolute position of the rotor is determined from the data structure according to the measured current from each of the coils. When the rotor is moving above the threshold speed, one or more rising or falling edges of magnetic field strength associated with the at least one rotating magnetic field device are sensed. At least one timing aspect of the rising and falling edges of magnetic field strength are compared to determine a second absolute position of the rotor.

  • Publication number: 20130115880
    Abstract: Techniques are provided for a client to send a message to a server comprising information configured to indicate that a user has logged on to the client. A determination is made as to whether the user logging on for the first time. When the user logs on for the first time, a message is received comprising a pseudo hardware address for a client wireless device associated with the client. The pseudo hardware address is assigned to the client wireless device. The client wireless device is paired with a wireless device associated with the user. A message is generated comprising pairing information for a pairing between the client wireless device and the user wireless device and the pairing information is sent to the server for storage. When the user subsequently logs on, a message is received comprising the pairing information and the client wireless device is provisioned with the pairing information.

  • Publication number: 20120261984
    Abstract: Disclosed herein are a variety of different electrical system topologies intended to mitigate the impact of large intermittent loads on a 12 volt vehicle power distribution system. In some embodiments the intermittent load is disconnected from the remainder of the system and the voltage supplied to this load is allowed to fluctuate. In other embodiments, the voltage to critical loads is regulated independently of the voltage supplied to the remainder of the system. The different topologies described can be grouped into three categories, each corresponding to a different solution technique. One approach is to regulate the voltage to the critical loads. A second approach is to isolate the intermittent load that causes the drop in system voltage. The third approach is to use a different type of alternator that has a faster response than the conventional Lundell wound field machine.

  • Patent number: 8140286
    Abstract: The linear position of a moving mechanical component is determined.

One or more compensations are applied to at least some of the plurality of best linear position estimates. Each of the compensations are applied to account for a relative positioning of one of the plurality of sensors with respect to the others. A plurality of weighting factors associated with each of the plurality of best linear position estimates are determined. The position of the mechanical component is determined using the plurality of best linear position estimates and the plurality of weighting factors.
