Abstract: A system comprises a photosensor and a controller. A first photoemitter transmits light onto objects at first height, a second photoemitter onto objects at second, lower height, and a third photoemitter onto objects at third, lowest height. The controller causes one of the photoemitters to transmit modulated light and the photosensor to receive reflections from a scene. The controller determines a depth map for the corresponding height based on phase differences between the transmitted and reflected light. In some examples, the system is included in an autonomous robot's navigation system. The navigation system identifies overhanging objects at the robot's top from the depth map at the first height, obstacles in the navigation route from a second depth map at the second height, and cliffs and drop-offs in the ground surface in front of the robot from the third depth map at the third height.

Abstract: The present invention discloses a system and a method for resource data classification and management. In operation, the present invention provides for evaluating a deployment probability score for each incoming data-record based on previous data-records. Further, a match score of each incoming data-record is computed. Furthermore, each incoming data-record is analyzed to determine a bench period associated with each incoming data-record. Yet further, the present invention, categorizes the incoming data-records into two or more categories based on corresponding deployment probability score, match score and bench period. A deployment opportunity index is generated for each incoming data-record representing the categories and corresponding probability score, match score and bench period, providing an upfront indication of deploy-ability of an incoming data-record. Finally, the present invention provides for generating a list of recommendations for each data-record.

Abstract: A method for designing a clock tree is disclosed. In one embodiment, a preliminary clock tree design for an integrated circuit (IC) is processed. The clock tree includes a root node, a number of intermediate levels, and a leaf level that is coupled to a number of clocked circuits. Clock gating circuits are placed at the leaf level of the clock tree, and at least some of the intermediate levels. Processing the preliminary clock tree design includes ensuring that an equal number of clock gating circuits are coupled between each leaf level clock gating circuit and the root node. After processing the preliminary clock tree design, clock tree synthesis is performed by executing a clock tree synthesis tool on a computer system to generate a synthesized clock tree design.

Abstract: A method of generating an area efficient power switch cell includes receiving, by a cell library design tool, a specification of a power switch circuit to be established as a power switch cell in a cell library. The cell library design tool also receives one or more attributes of the power switch cell including a height of the cell boundary and receiving, by the cell library design tool, a layout placement constraint requiring the power switch cell to be placed in a semiconductor layout so as to bridge two parallel rows of doped wells. The parallel rows of doped wells are interleaved with doped substrate and the doping of the wells is of a different type than that of the substrate. Based on the specification of the power switch circuit, the one or more attributes, and the layout placement constraint, the cell library design tool generates the power switch cell.

Abstract: Embodiments of an electromigration (EM) check scheme to reduce a pessimism on current density limits by checking wire context. This methodology, in an embodiment, includes applying existing electronic design automation (EDA) flows and tools to identify potentially-failing wires based on a worst-case EM check using conservative foundry current density limits. A more accurate, context-specific check can be performed on the potentially-failing wires to eliminate one or more of the potentially-failing wires if those wires do not experience worst-case conditions and meet current density limits based on an actual context of those wires. A designer can correct remaining wires which are not eliminated by the context-specific check.

Abstract: A time-of-flight (TOF) camera system for correcting non-linearity in phase-to-depth measurements. The TOF camera system includes a module to simulate movement of a target object by generating delays between modulation signals emitted from a transmitter and demodulation signals received by a sensor. For each delay, the TOF system calculates and stores a phase output corresponding to a simulated distance of the target object. The TOF camera may consult the stored data during normal operation to perform in-field calibration.

Abstract: In an embodiment, a methodology for designing an integrated circuit that attempts to improve power efficiency is provided. The methodology includes simulating the design under one or more power stimuli, where the power stimuli are known to cause high power consumption (e.g. in previous designs of the integrated circuit, the power stimuli may have caused power consumption). A set of nets within the integrated circuit may be identified that have the highest activity in the simulation (e.g. the highest amount of switching). The methodology may include providing data to the routing tool that is to route the nets in the integrated circuit. The data may indicate constraints for the set of nets, to help reduce dynamic power on these nets. Power efficiency of the integrated circuit may be improved if the routing tool is able to honor the constraints.
