Publication number: 20130307348Abstract: Example embodiments of the systems and methods of reduction of parasitic losses in a wireless power system disclosed herein provide a practical means of accurately estimating parasitic losses in a wireless power transfer system irrespective of coupling. Such systems and methods may be used to generate an equation which predicts parasitic losses in a wireless power system. In an offset case, in which the transmitter and receiver are not directly coupled, losses associated with the recirculating current in the primary LC tank dominate the loss, and the transmitted power may be better estimated by measuring the power inputs, power outputs, and injected losses in a controlled environment; making a mathematical fit to an equation, which from the various power measurements and injected loss, predicts the expected transmitter losses; and then, in an operational environment, using the equation to predict parasitic losses based on the power inputs, power outputs and expected loss equation.Type: ApplicationFiled: May 9, 2013Publication date: November 21, 2013Applicant: Texas Instruments IncorporatedInventors: Eric Gregory Oettinger, Vladimir Alexander Muratov, Ravindra Krishna Patil, Kalyan Siddabattula, William Ford Waters, III

Publication number: 20130308222Abstract: One embodiment includes a pulse duration control system for a magnetic disk-drive system. A rise delay system generates first control voltages in response to a write data input signal changing between a first state and a second state. A fall delay system generates second control voltages in response to the write data input signal changing between the first and second states. A comparator system generates a rising-edge overshoot signal and a falling-edge overshoot signal based on a comparison of the first and second control voltages. The rising-edge overshoot signal can set a duration of a positive overshoot current pulse for a write current at a transition of the write data input signal from the first state to the second state, and the falling-edge overshoot signal can set a duration of a negative overshoot current pulse for the write current at a transition from the second state to the first state.Type: ApplicationFiled: May 2, 2013Publication date: November 21, 2013Applicant: Texas Instruments IncorporatedInventor: Texas Instruments Incorporated

Patent number: 8588353Abstract: In conventional radio frequency (RF) systems, transmitters will usually convert baseband signals to RF so as to be transmitted. As part of the conversion process, the transmitters will perform digital predistortion (DPD), which uses feedback from a power amplifier. However, there are usually mismatches between the in-phase (I) and quadrature (Q) paths within with feedback loop. Traditional IQ correction filters were ineffective at providing adequate compensation for these mismatches, but here a filter is provided that provides adequate out-of-band compensation by use of frequency selectivity.Type: GrantFiled: April 1, 2011Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventors: Zigang Yang, Lars Jorgensen, Lei Ding

Patent number: 8588080Abstract: A system and method for using reserved resources in coexisting wireless networks. In one embodiment, a wireless apparatus includes a receiver, a network activity monitor, and a network access scheduler. The receiver is configured to identify a received network reservation message that inhibits access to a first wireless network for an interval defined in the reservation message. The network activity monitor is configured to monitor wireless activity on the first wireless network during the interval. The network access scheduler is configured to determine whether the reservation message prevents conflict of the first wireless network with a coexisting wireless network during the interval, and to schedule, based on a determination that the reservation message prevents conflict with the coexisting wireless network, the wireless apparatus to transmit on the first wireless network during the interval to a wireless device other than a wireless device identified in the reservation message.Type: GrantFiled: March 14, 2011Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventors: Yanjun Sun, Ariton E.

Patent number: 8589505Abstract: The specification discloses a system and related method for retrieving encoded media content, such as retrieving audio tracks from a CD in MP3 format. The system involves attaching indicia to the media, or possibly a case or protective cover of the media, which uniquely identifies the content. An encoding retrieval and playback device has the ability to obtain the unique number identified by the indicia, where obtaining the unique number may be a consumer entering the number, may be by reading a barcode label, may be by reading the number from a radio frequency device and the like. Once the unique number has been obtained, the encoding retrieval and playback device retrieves the encoded media content from a server across a network connection. In this manner, a consumer need only be present to initiate the retrieval process, and the retrieval of the encoded media content may be completed without the presence of the consumer, and without inserting the storage media in the playback device.Type: GrantFiled: November 27, 2002Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventor: Jason D. Kridner

Patent number: 8588154Abstract: A system and method for minimizing or preventing interference between wireless networks is disclosed. A network hub broadcasts a beacon signal within repeating beacon periods. The position of the beacon signal shifts within each beacon period based upon a predetermined pseudo-random sequence. The beacon signal includes data identifying the current beacon shift sequence and the current phase of the sequence. Neighboring hubs independently or jointly determine and broadcast their own beacon shift sequences and phases for their respective networks from a predetermined list. Nodes connected with the network hubs are assigned allocation intervals having a start time that is set relative to the beacon signal. The start time and duration of the allocation interval wraps around the beacon period if the allocation-interval would otherwise start or continue in a next beacon period.Type: GrantFiled: January 29, 2010Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventor: Jin-Meng Ho

Patent number: 8586130Abstract: An improved alignment structure for photolithographic pattern alignment is disclosed. A topographical alignment mark in an IC under a low reflectivity layer may be difficult to register. A reflective layer is formed on top of the low reflectivity layer so that the topography of the alignment mark is replicated in the reflective layer, enabling registration of the alignment mark using common photolithographic scanners and steppers. The reflective layer may be one or more layers, and may be metallic, dielectric or both. The reflective layer may be global over the entire IC or may be local to the alignment mark area. The reflective layer may be removed during subsequent processing, possibly with assist from an added etch stop layer, or may remain in the completed IC. The disclosed alignment mark structure is applicable to an IC with a stack of ferroelectric capacitor materials.Type: GrantFiled: September 24, 2010Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventors: Stephen Arion Meisner, Scott R.

Patent number: 8589748Abstract: Today many instances of IEEE 1149.1 Tap domains are included in integrated circuits (ICs). While all TAP domains may be serially connected on a scan path that is accessible external to the IC, it is generally preferred to have selectivity on which Tap domain or Tap domains are accessed. Therefore Tap domain selection circuitry may be included in ICs and placed in the scan path along with the Tap domains. Ideally, the Tap domain selection circuitry should only be present in the scan path when it is necessary to modify which Tap domains are selected in the scan path. The present disclosure describes a novel method and apparatus which allows the Tap domain selection circuitry to be removed from the scan path after it has been used to select Tap domains and to be replaced back into the scan path when it is necessary to select different Tap domains.Type: GrantFiled: December 4, 2012Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventor: Lee D.
