Publication number: 20160178537Abstract: A material-discerning device is arranged to include an antenna, a proximity sensor, a band pass filter and a processor. The antenna radiates a radio-frequency signal and a material object is located in the field created by the antenna and near the proximity sensor. Change in the amplitude of the radio-frequency signal due to the presence of the material object is detected by the proximity sensor. The change in amplitude of the radio-frequency signal is stored. The frequency of the radio-frequency signal is changed and the process is repeated until a range of frequencies have been swept and stored. After the range of frequencies has been swept and stored, the processor determines the type of material of the material object using the results of the changes in amplitude of the radio-frequency signals.Type: ApplicationFiled: December 22, 2014Publication date: June 23, 2016Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Alan H.

Publication number: 20160178450Abstract: An integrated circuit and method are provided for accurately measuring the temperature of a die of the integrated circuit. Pairs of diodes are driven with different currents in order to generate a series of thermal voltages. The ADC measures the series of thermal voltages against an external reference voltage. Based on these thermal voltage measurements, the ADC calculates the die temperature. The different currents used to generate the series of thermal voltages are selected at specific ratios to each other in order to promote the ability of the ability of the ADC to calculate the die temperature using standard components and logic of an ADC. These thermal voltages are generated and measured using integrated components of the die for which a temperature measurement is being provided, thus reducing several sources of inaccuracies in conventional die temperature measurement techniques. Addition embodiments are provided for detecting defective diodes based on comparisons of the thermal voltage outputs.Type: ApplicationFiled: October 28, 2015Publication date: June 23, 2016Applicant: Texas Instruments IncorporatedInventors: Dimitar Trifonov, Habib Sami Karaki

Patent number: 9374444Abstract: A system and method for providing a variety of medium access and power management methods are disclosed. A defined frame structure allows a hub and a node to use said methods for secured or unsecured communications with each other. Contended access is available during a random access phase.

Non-contended access is also available, and the hub may schedule reoccurring or one-time allocation intervals for the node. The hub and the node may also establish polled and posted allocation intervals on an as needed basis. The node manages power usage by being at active mode at times during the beacon period when the node is expected to transmit or receive frames.Type: GrantFiled: December 11, 2014Date of Patent: June 21, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Jin-Meng Ho

Patent number: 9374831Abstract: Embodiments of the invention provide coexistence among independent networks through active superframe interleaving. Network hubs and devices exchange signals over a selected channel only during active superframes of their network. Network hubs broadcast coexistence information during their active superframes. A hub of network B desiring to use the selected channel first attempts to fit its active superframes within network A's inactive superframes, if available. If network A is not providing inactive superframes, then the network B hub determines whether network A is willing to coexist using active superframe interleaving on the channel. If so, the network B hub sends an interleave request message to the network A hub, which may accept the message and send back an interleave response message. The network A hub then offers new inactive superframes, and the network B hub adapts the transmissions and receptions of network B to fit within these inactive superframes.Type: GrantFiled: September 12, 2011Date of Patent: June 21, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Jin-Meng Ho

Patent number: 9372808Abstract: This invention mitigates these deadlocking issues by a adding a separate non-blocking pipeline for snoop returns. This separate pipeline would not be blocked behind coherent requests. This invention also repartitions the master initiated traffic to move cache evictions (both with and without data) and non-coherent writes to the new non-blocking channel. This non-blocking pipeline removes the need for any coherent requests to complete before the snoop request can reach the memory controller. Repartitioning cache initiated evictions to the non-blocking pipeline prevents deadlock when snoop and eviction occur concurrently. The non-blocking channel of this invention combines snoop responses from memory controller initiated requests and master initiated evictions/non-coherent writes.Type: GrantFiled: October 22, 2013Date of Patent: June 21, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Matthew D Pierson, Daniel B Wu, Kai Chirca
