Title: Circuit and system of using junction diode as program selector for one-time programmable devices
Inventor: SHINE CHUNG
IPC: H01L27/24
Filed: 2014-09-19
Abstract: Junction diodes fabricated in standard CMOS logic processes can be used as program selectors for One-Time Programmable (OTP) devices, such as electrical fuses. At least one portion of the electrical fuse can have at least one extended area to accelerate programming. The program selector can be a diode or MOS that can be turned on through the channel or the source/drain junction. The OTP device can have the at least one OTP element coupled to at least one diode in a memory cell. A method of programming electrical fuses reliably is also disclosed. Advantageously, by controlled programming where programming current is maintained below a critical current, programming is reliable. In another embodiment, a programmable resistive device cell can use at least one MOS device as selector which can be programmed or read by turning on a source junction diode of the MOS or a channel of the MOS.

Title: Apparatus and method for single pass entropy detection on data transfer
Inventor: ASHWIN NARASIMHA
IPC: H04L29/06
Filed: 2016-06-13
Abstract: The present invention includes a memory unit and a processor coupled to a memory unit. The processor is operable to group a plurality of subsets of data from an input data stream, compute a first hash value corresponding to a first grouped subset of data and detect a match between the first hash value and a second hash value stored in a hash table. The processor is also configured to monitor a hash value match frequency for the input data stream by incrementing a counter value responsive to a detection of the match and determine an entropy level (i.e. the number of subsets having different values) for the input data stream based on the counter value relative to a frequent hash value match threshold. If the counter value meets or exceeds the frequent hash value match threshold, this indicates low entropy and data compression is initiated. However if the count fails to meet the threshold, this indicates high entropy and compression is not performed.

Title: In-vehicle device and route interpolation method therefor
Inventor: MASATO IEHARA
IPC: G07B15/06
Filed: 2014-02-21
Abstract: The purpose of this invention is to interpolate discontinuity intervals using interpolated routes that are appropriate from a toll-collection standpoint. This in-vehicle device (1) is provided with a map-information storage unit (12) that stores map information in which roads are artificially segmented into multiple links and each link is associated with unique identifying information and location information and an interpolated-route-information storage unit (14) that stores interpolated-route information in which combinations of two discontinuous line segments and line segments constituting interpolated routes that join said line segments are uniquely defined. If two line segments successively identified by a link identification unit (13) are discontinuous within the map information, a movement-route creation unit (15) uses the abovementioned interpolated-route information to interpolate the discontinuity interval.

Title: Learned model data processing
Inventor: EMRE BARIS AKSU
IPC: H04L9/00
Filed: 2016-08-19
Abstract: A neural network trained to act as a learned model which eg. recognises the speech of a particular user 12 is stored at a first processing system and, upon a request by a user for a network service, is sent to an associated virtual processing environment (eg. a Virtual Runtime Environment 20 run by an authenticated broker 14) at a second system for temporary storage and use in generating output which is subsequently provided to a third party provider 18. This allows users who do not wish their personal biometric data (eg. voice, image or fingerprint data) to be stored at remote servers to maintain access to service requiring eg. voice recognition, since the broker uses training data to create the neural network and then destroys the data.

Title: Controlling skidding vehicles
Inventor: IVAN NAVA
IPC: G05D1/00
Filed: 2017-08-07
Abstract: A method for controlling a skidding vehicle, the method including receiving a request for automated corrective measures to control the skidding 301, formulating a configuration change to at least one vehicle component in response to the request 303 and applying the change to mitigate the skidding 304. The request for automated measures may come from a driver, possibly using a button on a steering wheel, or may be implemented automatically from a skid detection module (232, fig.2); the action of which may be delayed depending on the skid severity, type or duration in order to determine if the driver is able to regain control of the vehicle. Cruise control or lane keeping systems may be used to control the steering angle, braking or acceleration to mitigate an oversteer, understeer or counter-steer skid. Sensors, such as LIDAR, RADAR, acoustic or ultrasound, may be used to perceive the environment surrounding the vehicle in order to aid in determining if a skid is underway.

Title: Determining strategic digital content transmission time utilizing recurrent neural networks and survival analysis
Inventor: Harvineet Singh
IPC: G06Q30/02
Filed: 2018-10-30
Abstract: The application concerns executing digital content campaigns, such as email marketing campaigns, using machine learning. Past emails to a user are partitioned into time bins 702. A recurrent neural network is trained on these past emails 704 and used to select a time bin during which a new email is sent to the user 706. The recurrent neural network may generate a predicted engagement metric for a past email based on the email’s time bin 704a, and then compare the predicted engagement metric to a ground-truth engagement metric for the past email 704b. The recurrent neural network may generate a hazard metric for one of the time bins 706a, where the hazard metric indicates the instantaneous probability that a user will interact with a new email sent during that time bin. The hazard metric may be based on a survival function embedded in the recurrent neural network. A schedule for sending multiple emails may be generated based on multiple time bins determined by the neural network. The time bins may span a planning window, and the past emails may be divided among the bins according to a grouping proportion.
