  • Patent number: 11467180
    Abstract: A distributed computing system for artificial intelligence in autonomously appreciating a circumstance context of a smart device. Raw context data is detected by sensors associated with the smart device. The raw context data is pre-processed by the smart device and then provided to a cloud based server for further processing. At the cloud based server, various sets of feature data are obtained from the pre-processed context data. The various sets of feature data are compared with corresponding classification parameters to determine a classification of a continuous event and/or a classification of transient event, if any, which occur in the context. The determined classification of the continuous event and the transient event will be used to autonomously configure the smart device or another related smart device to fit the context.

  • Publication number: 20220320014
    Abstract: In various embodiments, the present disclosure provides semiconductor devices, packages, and methods. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and an encapsulant on the die pad and the lead. A plurality of cavities extends into at least one of the die pad or the lead to a depth from a surface of the at least one of the die pad or the lead. The depth is within a range from 0.5 ?m to 5 ?m. The encapsulant extends into the plurality of cavities. The cavities facilitate improved adhesion between the die pad or lead and the encapsulant, as the cavities increase a surface area of contact with the encapsulant, and further increase a mechanical interlock with the encapsulant, as the cavities may have a rounded or semi-spherical shape.

  • Patent number: 11453123
    Abstract: A robotic device including one or more proximity sensing systems coupled to various portions of a robot body. The proximity sensing systems detect a distance of an object about the robot body and the robotic device reacts based on the detected distance. The proximity sensing systems obtain a three-dimensional (3D) profile of the object to determine a category of the object. The distance of the object is detected multiple times in a sequence to determine a movement path of the object.

  • Publication number: 20220293498
    Abstract: A semiconductor device, such as a Quad-Flat No-lead (QFN) package, includes a semiconductor chip arranged on a die pad of a leadframe. The leadframe has an array of electrically-conductive leads around the die pad. The leads in the array have distal ends facing away from the die pad as well as recessed portions at an upper surface of the leads. Resilient material, such as low elasticity modulus material, is present at the upper surface of the leads and filling the recessed portions. An insulating encapsulation is molded onto the semiconductor chip. The resilient material is sandwiched between the insulating encapsulation and the distal ends of the leads. This resilient material facilitates flexibility of the leads, making them suited for reliable soldering to an insulated metal substrate.

  • Patent number: 11404355
    Abstract: A semiconductor package includes a lead frame, a die, a discrete electrical component, and electrical connections. The lead frame includes leads and a die pad. Some of the leads include engraved regions that have recesses therein and the die pad may include an engraved region or multiple engraved regions. Each engraved region is formed to contain and confine a conductive adhesive from flowing over the edges of the engraved leads or the die pad. The boundary confines the conductive adhesive to the appropriate location on the engraved lead or the engraved die pad when being placed on the engraved regions. By utilizing a lead frame with engraved regions, the flow of the conductive adhesive or the wettability of the conductive adhesive can be contained and confined to the appropriate areas of the engraved lead or engraved die pad such that a conductive adhesive does not cause cross-talk between electrical components within a semiconductor package or short circuiting within a semiconductor package.

  • Patent number: 11398554
    Abstract: Transistors having partially recessed gates are constructed on silicon-on-insulator (SOI) semiconductor wafers provided with a buried oxide layer (BOX), for example, FD-SOI and UTBB devices. An epitaxially grown channel region relaxes constraints on the design of doped source and drain profiles. Formation of a partially recessed gate and raised epitaxial source and drain regions allow further improvements in transistor performance and reduction of short channel effects such as drain induced barrier lowering (DIBL) and control of a characteristic subthreshold slope. Gate recess can be varied to place the channel at different depths relative to the dopant profile, assisted by advanced process control. The partially recessed gate has an associated high-k gate dielectric that is initially formed in contact with three sides of the gate. Subsequent removal of the high-k sidewalls and substitution of a lower-k silicon nitride encapsulant lowers capacitance between the gate and the source and drain regions.

  • Patent number: 11397077
    Abstract: The present disclosure is directed to a system and method of controlling a facial recognition process by validating preconditions with a ranging sensor. The ranging sensor transmits a ranging signal that is reflected off of a user's face and received back at the ranging sensor. The received ranging signal can be used to determine distance between the user's face and the mobile device or to determine the reflectivity of the user's face. Comparing the distance to a range of distances corresponding to normal operation of the device or normal reflectivities associated with human skin tones can reduce the number of false positive activations of the facial recognition process. Furthermore, a multiple zone ranging sensor can produce a face depth map that can be compared to a stored face depth map or can produce a reflectivity map that can be compared to a stored face reflectivity map to further increase power efficiency and device security.

A structured light having patterned shapes are used in conjunction with the ranging sensor to receive reflected patterned shapes of the object. These reflected patterned shapes are used to analyze distance measurements associated with the specific patterned shapes. These distance measurements from both the ranging sensor and the image sensor is aligned and combined to generate an accurate depth map with high resolution using a processor of an electronic device including the ranging sensor and the image sensor.
