Abstract: Methods, systems, and devices for channel modulation for a memory device are described. A system may include a memory device and a host device coupled with the memory device. The system may be configured to communicate a first signal modulated using a first modulation scheme and communicate a second signal that is based on the first signal and that is modulated using a second modulation scheme. The first modulation scheme may include a first quantity of voltage levels that span a first range of voltages, and the second modulation scheme may include a second quantity of voltage levels that span a second range of voltages different than (e.g., smaller than) the first range of voltages. The first signal may include write data carried over a data channel, and the second signal may include error detection information based on the write data that is carried over an error detection channel.

Abstract: Systems, apparatuses, and methods for transmission failure feedback associated with a memory device are described. A memory device may detect errors in received data and transmit an indication of the error when detected. The memory device may receive data and checksum information for the data from a controller. The memory device may generate a checksum for the received data and may detect transmission errors. The memory device may transmit an indication of detected errors to the controller, and the indication may be transmitted using a line that is different than an error detection code (EDC) line. A low-speed tracking clock signal may also be transmitted by the memory device over a line different than the EDC line. The memory device may transmit a generated checksum to the controller with a time offset applied to the checksum signaled over the EDC line.

Abstract: A system aligns a 3D model of an environment with image frames of the environment and generates a visualization interface that displays a portion of the 3D model and a corresponding image frame. The system receives LIDAR data collected in the environment and generates a 3D model based on the LIDAR data. For each image frame, the system aligns the image frame with the 3D model. After aligning the image frames with the 3D model, when the system presents a portion of the 3D model in an interface, it also presents an image frame that corresponds to the portion of the 3D model.

Abstract: Methods, systems, and devices for error detection, error correction, and error management by memory devices are described. Programmable thresholds may be configured for a memory device based on a type of data or a location of stored data, among other aspects. For example, a host device may configure a threshold quantity of errors for data at a memory device. When retrieving the data, the memory device may track or count errors in the data and determine whether the threshold has been satisfied. The memory device may transmit (e.g., to the host device) an indication whether the threshold has been satisfied, and the system may perform functions to correct the errors and/or prevent further errors. The memory device may also identify errors in received commands or may identify errors introduced in data after the data was received (e.g., using an error detecting code associated with a command or bus).

Abstract: Various examples described herein are directed to systems and methods that learn to evaluate data items. A computing device receives data items and evaluates the data items. The evaluation performed by the computing device includes comparing a first data item with a second data item and determining a difference between the first data item and the second data item based on the comparison. The computing device also prepares a recommendation based on the difference between the first data item and the second data item and forwards the recommendation to a subject matter expert. The computing device receives an updated recommendation from the subject matter expert that is based on the recommendation. Using the updated recommendation, the computing device refines the comparing and determining operations where the computing device further learns to evaluate the data items by receiving the updated recommendation and refining the comparing and determining operations.

Abstract: An electrical network is equipped with feed-in devices, loads, a distribution grid arranged therebetween, at least one semiconductor switch, and at least one electromechanical switch for separating a feed-in device or a load in the event of a fault. The feed-in devices and loads are arranged in groups which are connected together by a busbar and paired semiconductor switches. Each feed-in device and load can be separated from the grid by an electromechanical switch in the event of a fault, and the individual groups of feed-in devices and loads can be separated from one another by the semiconductor switches in the event of a fault in order to prevent cross currents on the busbar.

Abstract: An electric grid includes feed-ins, loads, and a distribution grid, which is arranged therebetween. The distribution grid comprises at least one busbar and at least one device for opening or closing a DC circuit. The at least one device includes an electric switch for opening or closing the DC circuit, a fault current detector, a trigger unit, a precharging device, and a control unit for automatically closing the electric switch after the precharging process. The electric switch opens the DC circuit via the trigger unit if a fault current is detected by the fault current detector, and the precharging device restores the voltage on the busbar prior to closing the electric switch.

Abstract: The invention relates to a hydraulic machine, in particular to a hydraulic motor with two working lines, from one of which a high pressure line and from the other one a low pressure line is branched off. An electronic control unit and a servo displacement unit are provided to control the displacement of the displacement volume of a drive mechanism of the hydraulic machine, wherein the displacement volume can be determinated by the displacement of a servo piston within the servo displacement unit. For this, the servo piston can be loaded at least on one side via a servo pressure line with hydraulic fluid under servo pressure, wherein the servo pressure level can be adjusted by a control spool arranged moveable within a control valve. For this, hydraulic fluid from the low pressure line or, perhaps, from the high pressure line is guidable via the control valve to the servo pressure line if a suitable control signal is available at a switching valve.

Abstract: The present invention provides a method and a device for piercing a body part and determining whether a sufficient volume of blood has been withdrawn. A lancing element is rapidly inserted into a body part in a forward phase and retracted quickly to a lesser puncturing depth. Subsequently, the lancing element is retracted slower than during the first retraction movement and the distance retracted during the second retraction is shorter than the first retraction movement. During the second retraction movement, body fluid is collected in a collection phase by a capillary structure of the lancing element. Contact between the lancing element and the body fluid is detected after the forward phase at the beginning and the end of a waiting period.
