Abstract:
Die vorliegende Erfindung betrifft einen organisch gebundenen Trenn- oder Schleifkörper, der a. mindestens ein Bindemittel; b. mindestens einen teilchenförmigen Abrasivstoff; c. mindestens einen teilchenförmigen funktionellen Füllstoff umfasst, wobei das Bindemittel den teilchenförmigen Abrasivstoff und den teilchenförmigen funktionellen Füllstoff umschließt und wobei der funktionelle Füllstoff mindestens zwei Metalle umfasst, die eine schmelzflüssige Phase in einem Temperaturbereich von 100 bis 300°C bilden.
Abstract:
A high-speed current sense amplifier has complementary reference cells and load devices that eliminate capacitive mismatch contributions. The current sense amplifier includes a voltage comparator, a first clamping device coupled between a first input of the voltage comparator and a first input signal node. The first clamping device is coupled to a reference voltage. A second clamping device is coupled between the second input of the voltage comparator and a second input signal node. The second clamping device is also coupled to the reference voltage. A current mirror is coupled between the first and second input of the voltage comparator and is coupled to an active capacitance balancing circuit. The active capacitance balancing circuit may be combined with the voltage comparator. Equalization devices may be coupled between the first and second inputs of the voltage comparator, and between the first input signal node and the second input signal node.
Abstract:
A system, method and apparatus are provided for enabling mobile payments for purchases from selected merchants via a client device. A client application installed on a client device can make payments and submit shipment information when making purchases. The client application securely stores user-related payment information locally on the client device, where such information only needs to be entered once upon initialization of the client application. The client application facilitates payment transactions by forwarding user-related payment information for purchases to a payment server when authorized by a user. When making a purchase, a user can enter an identification code into the client application that identifies a product or service, where the identification code and user-related payment information are forwarded to the payment server. The payment server uses the code to retrieve details about the purchase and performs operations to complete the purchase using the received user payment-related information.
