Abstract: Disclosed herein are system, method, and computer program product aspects for simulating map update functions in an autonomous vehicle (AV) system. The system can create a simulation environment to test the AV system using data collected during regular operations of the AV system. The data comprises (1) map updating documents from a cloud service, (2) local map updating documents, and (3) observation data. A map-deviation detection mechanism is used to process the observation data.

Abstract: Disclosed are systems and methods of communicating an attribute of an artificial intelligence (AI) agent system through an interface. The methods comprise receiving input data, determining attribute values of attributes to the input data over temporal periods, determining interface attribute values representing the interface attributes and communicating the interface attribute values to a dynamic interface. Also disclosed is a contextualized system comprising a contextualizer module and a user interface configured to communicate a recommended data to a user. In some embodiments, the contextualizer module selects a most pertinent data as the recommended data based on an activity of the user.

Abstract: An enhanced exoskeleton system is disclosed comprising an exoskeleton, a base layer comprising at least one sensor, an exoskeleton actuator configured to actuate the exoskeleton, a control subsystem comprising one or more processors, and memory elements including instructions that, when executed, cause the processors to perform operations comprising: receiving sensor data from the sensor, determining a future movement intent of a user of the exoskeleton, determining a command for an exoskeleton actuator based on the future movement intent, and communicating the command to the exoskeleton actuator whereby the exoskeleton is actuated by the exoskeleton actuator. In some embodiments, the sensor data comprises an anticipatory data value from an anticipatory sensor. In some embodiments, the sensor data comprises an anticipatory data value from an electromyography (EMG) sensor.

Abstract: A welding shield includes a frusto-conical metal shield member, open at top and bottom, and including a wall opening for welding gun access. A lens is removably mounted in the top of the shield member, and a horizontal metal screen is removably mounted within the shield member between wall opening and lens. A circumferential base around the bottom is of a flexible and nonflammable material for effective closure around a weld work area. The work area is viewable, magnified, by the lens. The welding shield is lightweight for easy movement and placement by one available hand of the user.

Abstract: A showering system comprising a first tank, a first and second pump, a water heater, a shower head, a shower base and a valve; wherein water for a shower is stored in the first tank from which it is pumped via the first pump through the water heater to the shower head whence from the water falls to the shower base and passes to the valve from which the water is either discharged to a sewer or pumped via the second pump back to the first tank.

Abstract: A stringed musical instrument device that functions as a peripheral for a computer or computing device, whereby electronic transducers placed inside and/or outside the instrument convert the vibrations of the strings and/or the instrument body from an analog electrical signals to digital signals. The digital signals are then transmitted via Class Compliant USB and/or FireWire-IEEE 1394 and/or IEEE 802.11 wireless and/or Bluetooth® wireless protocols to any computer or computing device that accepts data via those protocols. This device requires no external power, amplification, analog-to-digital conversion, software or hardware. This device is an improvement over the prior art in that it accurately and immediately represents on a computer or computing device the signals that are being sent from the instrument and reduces the number of devices needed to accomplish the task of sending digital signals to a computer or computing device.

Abstract: A new power tong for rotating tubular members for make-up (connection) and break-out (disconnection) operations. In one aspect such a tong has at least one movable jaw with a smooth surface gripping element thereon and pre-load apparatus for applying a pre-load force to a movable jaw so that the jaw does not slip on a tubular to be rotated and so it does not mark or damage the tubular. In one aspect the pre-load apparatus includes a first pre-load device at one end of a movable jaw for breakout operations and a second pre-load device at another end of the jaw for make-up operations. In one aspect a power tong which has unique smooth surfaced jaw inserts made, e.g., of aluminum. In one aspect a single pivotable pre-load cylinder, fixed to rotary, pivots for pivotable connection to one jaw or the other. This can be done manually or a powered smaller piston/cylinder may be used to pivot the pre-load cylinder.

Abstract: An electrical connector comprising: a housing assembly (328, 318) having at least one slot (562) extending substantially therethrough; a releasable positive stop (636, 638) on the housing assembly; at least one lock (632) on the housing assembly; a slide assembly (312 and 314) slidably received within the at least one slot; and at least one locking wall (650) on the slide assembly, wherein, in initial engagement of the slide assembly to the housing assembly where the slide assembly is slid into the at least one slot in an engagement direction, the positive stop prevents movement of the slide assembly beyond a prestage state, wherein, in the prestage state, the lock engages the locking wall preventing disengagement of the slide assembly from the prestage state. Thus, an advantageous prestage state of the electrical connector is achieved.

Abstract: An electrical connector comprising: an outer housing including a plurality of receptacles; a cavity within the outer housing; a first inner housing within the cavity, wherein the first inner housing includes a first plurality of flexible extensions on a first end of the first inner housing; a first plurality of cylindrical openings within the first inner housing; a first plurality of conductive terminals, wherein a portion of each conductive terminal of the first plurality of conductive terminals extends through one of the cylindrical openings of the first plurality of cylindrical openings and out of the first inner housing and is received in one of the receptacles of the plurality of receptacles, wherein each conductive terminal of the first plurality of conductive terminals is maintained locked in place by a corresponding one flexible extension of the first plurality of flexible extensions; and a plurality of access holes on the outer housing, wherein each receptacle has located proximate thereto one of the

Abstract: A header connector snap lock apparatus for securing a header connector to a printed circuit board through insertion of semicircular header connector pegs into corresponding circular printed circuit board openings allowing for circuit board thermal expansion, for example during a wave solder process, and dispersing peg strain concentration through insertion force deflection of the peg and the beam along at least three deflection planes through use of a channeled, slotted cantilever beam extending out from the header connector and from which the peg extends.
