US12045307B2 Fine-grained per-vector scaling for neural network quantization
Today neural networks are used to enable autonomous vehicles and improve the quality of speech recognition, real-time language translation, and online search optimizations. However, operation of the neural networks for these applications consumes energy. Quantization of parameters used by the neural networks reduces the amount of memory needed to store the parameters while also reducing the power consumed during operation of the neural network. Matrix operations performed by the neural networks require many multiplication calculations, so reducing the number of bits that are multiplied reduces the energy that is consumed. Quantizing smaller sets of the parameters using a shared scale factor improves accuracy compared with quantizing larger sets of the parameters. Accuracy of the calculations may be maintained by quantizing and scaling the parameters using fine-grained per-vector scale factors. A vector includes one or more elements within a single dimension of a multi-dimensional matrix.

US12043999B2 Drainage system for pressure-assisted flush water tank
A drainage system for a pressure-assisted flush water tank includes a tank main body and a drainage structure. The drainage structure includes an accommodating chamber and a membrane. The accommodating chamber has a drain outlet, a water inlet, and a drainpipe. The membrane partitions the accommodating chamber into a back-pressure chamber and a drainage chamber and is provided with a supplement hole that communicates the back-pressure chamber with the drainage chamber. The drain outlet is communicated with the back-pressure chamber, while the water inlet and the drainpipe are both communicated with the drainage chamber. The tank main body defines therein a storage chamber communicated with the water inlet. The membrane moves toward or departs from the drainpipe as a pressure in the back-pressure chamber varies so as to close or open the drainpipe.

US12043996B2 Retracting shower hose apparatus and method
A retractable shower hose apparatus (11) has a housing enveloping a reel (21) mounted for rotation around an irrotatably axle (18). The axle (18) has a lumen (20) communicable with a shower valve supply of water whereby water can reach an axle port (19) disposed in a chamber (22) formed around the axle within the reel. The chamber (22) communicates with a shower hose reel coupling on the periphery of the reel to deliver water to the bore of the shower hose (24, 26). The reel has a depth equal to the diameter of the hose and is confined between closely fitting front and rear panels (12, 13) of the housing so that the hose can only coil radially out from the axis to a lead through (10). A coil spring (21.9) is disposed in the chamber (22) to act between the axle and reel and forcibly urge the hose to coil around the reel and retract into the housing.
US12043993B2 Ablutionary installation
A diverter for use in a shower system, the diverter having a diverter inlet and at least two diverter outlets. The diverter inlet is provided with a diverter inlet fitting adapted to be connected to a hose or pipe. The diverter inlet fitting is freely movable about an axis of the diverter.
US12043990B2 Track following system, track following method, and computer readable medium
A convergence determination unit determines whether a state of the bucket has converged to a current target state. A target state update unit is configured to update a target state of the bucket when the convergence determination unit determines that the state of the bucket has converged to the current target state. The convergence determination unit includes a first convergence determination unit and a second convergence determination unit. The first convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a first convergence condition. The second convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a second convergence condition, which is stricter than the first convergence condition.
US12043983B2 Construction machine
An object of the present invention is to provide a construction machine that can use the return oil from a hydraulic actuator effectively. For this purpose, a controller computes a flow rate of the return oil from a first hydraulic actuator on the basis of an operation signal from a first operation device, computes a flow rate of oil to be supplied to a second hydraulic actuator on the basis of an operation signal from a second operation device, sets smaller one of the flow rate of the return oil and the flow rate of the oil to be supplied, as a regeneration flow rate that is a flow rate of oil to be regenerated in the second hydraulic actuator, sets a flow rate obtained by subtracting the regeneration flow rate from the flow rate of the return oil, as a recovery flow rate that is a flow rate of oil to be recovered to a pressure accumulating device, adjusts an opening degree of a first control valve 2 such that a flow rate of oil supplied from the first hydraulic actuator to the pressure accumulating device coincides with the recovery flow rate, and adjusts an opening degree of a second control valve such that a flow rate of oil supplied from the first hydraulic actuator to the second hydraulic actuator coincides with the regeneration flow rate.
US12043982B2 Remote operation support system and remote operation support method
A system or the like capable of making an operator recognize an environment around a working machine in an appropriate form in consideration of a state of the working machine. In the case where a working machine 40 is in a first state (an operable state), a display magnification of a captured image (environment image) outputted to a remote output interface 220 is controlled only in a range of a specified display magnification or lower, or is fixed at a value of the specified display magnification or lower. On the other hand, in the case where the working machine 40 is in a second state (an inoperable state), a zoom function of an actual machine image capturing device 412 is demonstrated according to a zoom operation through a remote input interface 210 by the operator.
