Abstract: Systems and methods are provided for using a distributed cache architecture with different methods to load balance requests depending upon whether a requested data item is a freely-requested item (e.g., a “hot key”). The cache may be implemented as a consistent hash ring, and most keys may be assigned to particular node based on a consistent hash. For hot key requests, the requests may be distributed among a subset of nodes rather than being assigned to a specific node using consistent hashing. When a witness service is used to ensure that cached data is fresh, verification requests for data regarding hot keys may be batched to avoid overloading the witness service with hot key requests.

Abstract: A laundry kiosk is provided according to an aspect of the present disclosure. In an embodiment, the laundry kiosk contains a user interface component to receive laundering choices for a garment from a user and an apparatus to process the garment according to the received choices. The laundering choices include one or more of a combination of cleaning, pressing and drying. A suitable enclosure is also provided to hold the apparatus and the user interface component.

Abstract: A context switching system includes a processor and a scheduler. The processor is configured to execute a first thread. A first context associated with the first thread is stored in a register set of the processor. While the first thread is being executed, the scheduler is configured to select a second thread from a set of threads, and receive and store a second context associated with the second thread in a register set of the scheduler. The second thread is to be scheduled for execution after the first thread. The scheduler is further configured to swap the first and second contexts when the execution of the first thread is halted, thereby executing the context switching. Further, the processor is configured to execute the second thread based on the second context. While the second thread is being executed, the first context is stored in the data memory.

Abstract: A radar and/or camera system may include a receiver subsystem that receives image and/or radar data from one or more imaging/radar subsystems via multiple data lanes. A vision processor of the system may receive a data stream that includes the image and/or radar data and one or more synchronization signals including a vertical sync signal. The receiver subsystem may include a timing event generator that toggles the vertical sync signal in response to detecting certain timing event errors in order to correct these timing event errors without interrupting normal operation of the system. The receiver subsystem may include sync monitoring circuitry that may detect synchronization errors that occur when synchronization signal pulses received by the receiver subsystem do not match a predefined synchronization pattern within a scan window of predefined length. The system may be reset in response to detection of such synchronization errors.

Abstract: A laundry apparatus contains a steamer for providing steam, a first unit for blowing the steam towards a fabric and a second unit for blowing a hot gaseous matter towards the fabric, wherein the hot gaseous matter is formed by heating the gaseous matter also with the steam. An apparatus for removing wrinkles from garments contains a hanger for hanging a garment, a steam tube to blow steam into a sleeve of the garment, and an expandable component underneath the shoulder. The expandable component is in a compact state when the sleeve of the garment is initially hung from the shoulder, and in an expanded state to close the passage between the sleeve and a torso of the garment, wherein the steam blocked by the expandable component operates to remove wrinkles in the sleeve.

Abstract: A system and method for real-time data transfer on a system-on-chip (SoC) allows MIPI-CSI (camera serial interface) data received on a first interface to be output on another MIPI-CSI interface without using system memory or delaying the loopback path. The system includes a CSI receiver, a loopback buffer, and a CSI transmitter. The loopback buffer is used for the data transfer between the CSI receiver and the CSI transmitter. The CSI transmitter receives a payload included in a data packet from the CSI receiver by way of the loopback buffer. The CSI receiver communicates a packet header of the data packet to the CSI transmitter. The CSI transmitter reads the payload from the loopback buffer based on the packet header and at least one of a buffer threshold capacity and payload size.

Abstract: A system may include a plurality of playback paths comprising an open-loop playback path configured to drive an output load and a closed-loop playback path. The closed-loop playback path may include an outer feedback loop comprising one or more integrators, a quantizer, and an output driver for driving the output load, the outer feedback loop having an outer loop feedback gain and an inner feedback loop comprising the one or more integrators and the quantizer and excluding the output driver, wherein the inner feedback loop has a variable inner loop feedback gain which is adjustable to match the outer loop feedback gain.

Abstract: A method of enhancing log packets with context metadata is provided. The method at a redirecting filter on a host in a datacenter, intercepts a packet from a data compute node (DCN) of a datacenter tenant. The method determines that the intercepted packet is a log packet. The method forwards the log packet and a first set of associated context metadata to a proxy logging server. The first set of context metadata is associated with the log packet based on the DCN that generated the packet. The method, at the proxy logging server, associates a second set of context metadata with the log packet. The second set of context metadata is received from a compute manager of the datacenter. The method sending the log packet and the first and second sets of context metadata from the proxy logging server to a central logging server associated with the tenant.
