Abstract: A circuit includes an output current circuit that employs a regulated voltage to provide an output voltage to drive a load current through an output load resistor. A load resistance sensor (LRS) senses the resistance of the output load resistor based on the output voltage and the load current. A controller provides a sense voltage control command to set the regulated voltage to an initial sense voltage during a sense mode. The initial sense voltage adjusts the output voltage of the output current circuit and enables the LRS to sense the resistance of the output load resistor at a given setting of the load current. The controller provides a clamp control command based on the sensed resistance of the output load resistor to set the regulated voltage to a fixed regulated voltage during an operation mode. The fixed regulated voltage enables the output current circuit to supply a predetermined maximum load current to the output load resistor at a predetermined minimum setting of the output voltage.

Abstract: Embodiments provide methods, and systems for encrypting data for web aplication. A method includes receiving, by a server system, a cryptographic certificate including asymmetric key pair. The method includes generating a random value key that forms at least a part of a Content Encryption Key (CEK) to be generated by a web application. The method includes sending the random value key to a client device running the web application over a secure network communication channel for generating the CEK. The CEK is to be utilized for encrypting a content entered by a user of the web application on the client device and the CEK is encrypted using a public key of the asymmetric key pair for transmission over the secure network communication channel. Furthermore, the method includes translating, the CEK encrypted under public key to CEK encrypted under LMK using a private key being part of the asymmetric key pair.

Abstract: A separator (10, 60, 65, 100) is disclosed for electrically separating groups of end windings (52) in the stator of a rotating electrical machine. The separator is arranged to provide circumferential air channels (24, 74, 85) through the windings. This can allow air flow to be delivered to inside the windings, thereby cooling the windings more effectively.

Abstract: A buck-boost regulation methodology operable, in one embodiment, with a single inductor, four-switch (S1-S4) buck-boost regulator configured for DCM. Buck-boost transition switching control is operable when inductor charge time exceeds a max charge time, and inductor discharge time exceeds a max discharge time, and includes: (a) during charge transition cycles, at the end of the max charge time, if IL is less than a predetermined peak current IL—MAX, switching S2 on (grounding the output side of the inductor) and S4 off, causing IL to increase (a rapid S1S2 charging current ramp), until IL reaches IL—MAX, and (b) during discharge transition cycles, at the end of the max charge time, if IL is greater than zero, switching S1 off and S3 on (grounding the input side of the inductor), causing IL to increase (a rapid S3S4 IL discharging current ramp), until IL reaches zero.

Abstract: A method reading bank register values is provided. Register values are stored in a readback bank. The register values are output sequentially from the serial bank. An indicator is received by the serial bank. A determination is then made as to whether the indicator was received by the serial bank prior to completion of the outputting of the register values. If the indicator was received prior to completion of the outputting of the register values, the register values are loaded into the serial bank from the readback bank.
