  • Publication number: 20220059020
    Abstract: Addressing an emissive display having pixels arranged into rows and columns. A first clock signal is received at an address select input of a first row of the display. Data signals are received at data signal inputs of the first row of the display, each of the received data signals corresponding to a column of the display. When the first clock signal is active at the address select input, the data signals are output to corresponding drivers of light emitting semi-conductors of the first row and via corresponding data signal outputs of the first row. The data signals are received from the data signal outputs of the first row at a first row of shift registers. A second clock signal is received at the first row of shift registers. When the second clock signal is active, the data signals are output from the first row of shift registers.

  • Patent number: 11182647
    Abstract: In one embodiment, a method for tracking includes capturing a first frame of the environment using a first camera, identifying, in the first frame, a first patch that corresponds to the first feature, accessing a first local memory of the first camera that stores reference patches identified in one or more previous frames captured by the first camera, and determining that none of the reference patches stored in the first local memory corresponds to the first feature. The method further includes receiving, from a second camera through a data link connecting the second camera with the first camera, a reference patch corresponding to the first feature. The reference patch is identified in a previous frame captured by the second camera and of the second camera. The method may then determine correspondence data between the first patch and the reference patch, and tracks the first feature in the environment based on the determined correspondence data.

  • Publication number: 20210305748
    Abstract: A magnetic connector assembly has a female connector with spring-loaded conductive pins slightly protruding inside a recess or cavity in the female connector's body. A corresponding male connector has a protrusion on its body with conductive pins slightly indented into the protrusion's surface. The protrusion on the male connector is sized and shaped to fit into the cavity in the female connector such that the male connector's pins engage the pins of the female connector, allowing for electrical communication across the connector assembly. Magnets on the male and female connectors secure them in a correct orientation. A unique shape ensures proper alignment of the pins and prevents the connection of incompatible devices.

  • Publication number: 20210224221
    Abstract: An apparatus includes a first device having a clock signal and configured to communicate, via a data bus, with a second device configured to assert a data strobe signal and a plurality of data bit signals on the data bus. The first device may include a control circuit configured, during a training phase, to determine relative timing between the clock signal, the plurality of data bit signals, and the data strobe signal. The first device may determine, using a first set of sampling operations, a first timing relationship of the plurality of data bit signals relative to the data strobe signal, and determine, using a second set of sampling operations, a second timing relationship of the plurality of data bit signals and the data strobe signal relative to the clock signal. During an operational phase, the control circuit may be configured to use delays based on the first and second timing relationships to sample data from the second device on the data bus.

  • Patent number: 11019701
    Abstract: LED structures (e.g., LED arrays) and fabrication methods can reduce or even eliminate deep etching, and associated defect formation, proximate sites of individual LEDs. Such approaches can achieve desired electrical isolation without deep etching, provide a high conductivity current spreading layer, and, or reduce losses otherwise associated with conventional fabrication approaches. Some implementations advantageously lift off or separate an insulating substrate from a wafer to expose a bottom surface of the epitaxial LED layer and forms a backside contact (e.g., ground plane) overlying the bottom surface. Other implementations isolate deep etching away from sensitive regions and locate the backside contact on a top surface of the epitaxial LED layer. Some implementations form light extraction features (e.g., photonic crystals) on the exposed bottom surface. The top surface of the epitaxial LED layer may be undoped to improve electrical isolation.

  • Publication number: 20200166774
    Abstract: A temple bar cam is disclosed that, when used in pairs, sustains a pair of eyeglasses so that the nose pads remain above a wearer's nose. One temple bar cam is placed on each temple bar of a pair of eyeglasses. As the eyeglasses are placed on a wearer's face, the temple bar cams rotate into the user's temples, causing the eyeglasses to cease downward movement and holding the eyeglasses in place just above the user's nose. The temple bar cams may be made of a soft, elastic, and nontoxic material, such as medical grade silicon, for the wearer's comfort. The wearer's comfort is further enhanced by the frustum shape of the temple bar cams, and a bore extending through each temple bar cam in order to increase deformability of the temple bar cam's shape.
