Title: Toaster
Inventor: HARSIMRANJIT SINGH
IPC: A47J37/08
Filed: 2021-02-18
Abstract: An apparatus for toasting a food article (10, Fig 1) comprises a body (11, Fig 1) defining an interior heating station, an electrically powered heat source (elements) (13, Fig 1) and a switch or dial (16, Fig 1) for controlling the exposure of the food article to the heat source. The food article exposure to the heat source is a heating cycle with a first heating phase for a first time period, Step 44, and a second heating phase for a second time period, Step 46. The first and second time periods may be separated by an interval. Preferably the heat source operates at a first level during the first heating phase and / or a second level during the second heating phase. The first and second levels may be substantially the same. The switch may automatically control the heat source to repeat the heating cycle and / or control the exposure of the food article to the heat source by physically changing the proximity of one to the other. A means to direct cooling air, which could be refrigerated, towards the food article during a heating phase(s) may be included. A method of control is also claimed.

Title: Automatic annotation of drivable road segments
Inventor: Sergi Adipraja Widjaja
IPC: G01C21/00
Filed: 2022-02-09
Abstract: Provided are techniques for automatic annotation of drivable road segments, including but not limited to: receiving sensor data, generating a map, dividing the map into disjoint sub-maps, inferring sub-map segmentation masks, constructing an inferred segmentation mask, filtering the inferred segmentation mask based on a threshold, smoothing the filtered segmentation mask to generate a smoothed segmentation mask with at least one continuous drivable road segment based on at least one criterion, planning a path for a vehicle and controlling the vehicle. The sub-map segmentation masks are inferred using a machine learning model trained with positive examples containing part of a drivable road segment. In examples, the drivable road segments are identified in birds-eye-view data, such as merged maps. Pixels of the sub-map may be identified as corresponding to a drivable road segment by applying a sliding window across at least one sub-map segmentation mask and updating via backpropagation the weights of a convolutional neural network based on output labels bounded by the sliding window and ground truth data.

Title: Valve
Inventor: JOHANNES PETRUS STROEKEN
IPC: F16K1/38
Filed: 2022-04-04
Abstract: The valve includes an inlet 50 and an outlet 52. A flow path connects the inlet and the outlet. A valve seat 54 is positioned in the flow pat. A closure member 62 is movable between a closed position where it is located against the seat and inhibits flow of medium throught he flow path. A barrier arrangement 74, such as a piston prevents backflow through the outlet when the closure member is closed. Also claimed is a valve which inhibits the passage of solid particles when the closure member is in the open position, possibly with seal 68. Also claimed is a pressure exchange chamber with the valve. Also claimed is a pressure exchange chamber pumping system kit with a pressure exchange chamber and a number of valve arrangements. Also claimed is a valve closure unit with ends in flow communication. Also claimed is a method of modifying a pressure exchange chamber with the valve.

Title: Implementing a scatter function on a neural network accelerator
Inventor: LE YANG
IPC: G06N3/06
Filed: 2022-10-31
Abstract: One or more vectors of indices are converted to sparse index tensors in a one-hot sparse format. An update tensor is generated, by applying the update values to one of the sparse index tensors (or a tensor derived from it). In some examples, an input data tensor is updated based on the update tensor. The update tensor may contain a plurality of input values to be updated. A sparse index tensor may be summed over one direction to calculate a reduced sparse index tensor, and element-wise multiplication performed. The neural network accelerator may use a delta function for clamp operation and a memory manipulation module to perform transpose, permute and repeat operations. This may be used in robotics or autonomous vehicles where Lidar produces a point cloud of object detection. The scatter operation may be used in steganography or watermarking.

Patent GR-910100267-A (GR)
Title: Dripper incorporable in a single - or double -wall drip irrigation pipe made of polymer with a bump that automates the opening of holes on the irrigation pipe and a device for opening such holes
Inventor: MENEXIADIS KONSTANTINOS
IPC: A01G25/02
Filed: 1991-06-13
Abstract: The invention at hand refers to a water dripping unit (dripper) that has all operational characteristics of hitherto known and used drippers intended to be incorporated in a single or double walled tube made of polymer material, yet it differs from such because it is equipped with an extension that has a proper cut made next to the water exit. This extension, along with the part of the irrigation tube that surrounds it, is cut off during the production process by a proper layout of an ambient or stable cutting knife or instrument or otherwise, thus creating the hole in the tube's wall that permits communication of the water exit chamber with the surrounding space. This drilling is done simply during the passing of the extension through the cutting device, without need of expensive and complex electronic devices that would determine the exact location of the hole and would activate the drilling device, and without the possibility of any drilling taking place or drilling made in a wrong location that would result in a faulty irrigation tube.

Date Oct. 9, 1986.An apparatus for the automatic determination of a continuous bulk material throughput through a continuous balance comprises a weighing vessel, an adjustable closure member for adjusting an outlet cross-section of the weighing vessel and an electronic weight difference measuring device. The closure member is connectable to the weighing vessel in the outlet region thereof which is formed as an adjustable wall part and is so arranged that when the closure member is in the open operating position, there is a free mass flow in the weighing vessel. Simultaneously it is ensured that the bulk material flows freely and unhindered from the outlet of the weighing vessel. In the process of the automatic determination of the bulk material throughput while using the apparatus either when maintaining a mass flow in the complete weighing vessel or with the mass flow stopped, a signal corresponding to the weight change in the weighing vessel per unit of time is derived and used for calculating the parameters of state of the bulk material flow.

Abstract: A watch has a dial with numerals 1 through 12 circumferentially distributed thereon in a random sequence. The current time is indicated by the watch hands notwithstanding this random sequence of numerals, together with a digital display of the current time. The minute hand makes an abrupt large angular movement every five minutes to the relevant position indicating the minute of current time, while the hour hand makes an abrupt large movement for every hour to the relevant position indicating the hour of current time. When the minute hand reaches the position of numeral 12, the hour hand abruptly moves through a large angular distance to indicate the current hour. Drivers rotate the minute and watch hands in accordance with a predetermined stored program.
