Title: Metalworking system with force controlled wire feed start operation
Inventor: Wagner Dustin
IPC: B23K26/70
Filed: 2016-09-14
Granted: 2023-10-17
Abstract: A method for controlling a start of a metalworking operation. The method includes detecting an initial contact between a wire being fed from a welding apparatus and a workpiece and, in response to the detection, halting feeding of the wire from the welding apparatus. The method further includes activating a high energy heat source configured to heat a tip of the wire and resuming the feeding of the wire from the welding apparatus when the tip of the wire is heated by the high energy heat source to a plastic state. The feeding of the wire is resumed by measuring a force feedback from the wire contacting the workpiece. An apparatus for implementing the method is also disclosed.

Title: Phonepad
Inventor: ZHAO PENGXIANG
IPC: H04M1/72412
Filed: 2015-08-23
Granted: 2023-01-24
Abstract: Example apparatus and methods concern a first device (e.g., phone) having a first set of input or output capabilities interacting with a second device(s) (e.g., tablet) having a second set of input or output capabilities. The first device may detect the second device and establish a communication link with the second device. The first device may receive inputs presented at the second device and provide outputs to be presented by the second device. In response to an action (e.g., touch, gesture) on the second device, an application running on the first device may receive an input, which may in turn determine an output that is provided to the second device. The first device may use the second device to provide an input/output experience that is superior to what the first device could provide with its own built-in input/output components. The combination saves energy and reduces computing complexity.

Abstract: A needle employs a three-stair-stepped structure including a front-end small diameter part, an intermediate part, and a large diameter part . The front-end small diameter part and the intermediate part are in fluid communication with each other by the first tapered part, and the intermediate part and the large diameter part are in fluid communication with each other by the second tapered part. The internal diameter of the front-end small diameter part is made so as to be equal to or greater than 0.35 mm based on the allowable deformation level of a cumulus oocyte complex, the outer diameter is made so as to be equal to or smaller than 0.7 mm based on the size of a small follicle, and the inclination angle of the inclined acicular end, and the length is made so as to be 10-25 mm based on the size of a dominant follicle.  The internal diameter of the intermediate part is made so as to be equal to or greater than 0.45 mm based on the size of the cumulus oocyte complex. The internal diameter of the first tapered part is formed at an average gradient of equal to or smaller than 10% so as to suppress an abrupt recovery of the cumulus oocyte complex from a deformed condition at the time of suction, and the total length from the front-end small diameter part to the intermediate part is made so as to be a length that does not allow the large diameter part to be inserted in human tissue.

The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

Patent CA-3031564-C (CA)
Inventor: GONG ZHE
IPC: G01R31/36
Filed: 2018-07-13
Granted: 2019-05-14
Abstract: The present disclosure provides electrical architecture for electrochemical impedance spectroscopy (EIS). An EIS circuit comprises at least two current regulators and an electrical energy storage device, which are connected with one or more electrochemical cells in a configuration that decouples power flowing into the respective current regulators. The presence of the electrical energy storage device enables each regulator to operate simultaneously at lower power levels while inducing the desired EIS perturbation current. Operation at low power allows lower volume and cost for the same current compared to only dissipative or non-dissipative current regulators. Further, the electrical energy storage device allows the power flowing through the current regulators to be varied independently in order to achieve the desired EIS perturbation current while a minimum amount of heat is generated in the circuit, thus allowing the circuit to occupy minimal size and incur minimal cost.
