Exemplary embodiments of the invention include a request received to change a TX output power setting or a frequency channel setting. In response, the requested TX output power setting is used to generate a TX output signal in the proper frequency channel. Handset circuitry makes OOB power measurements, the results of which are used to determine a VCC2 setting. The VCC2 setting is a setting that results in an MPS requirement just being met. The VCC2 setting is stored in association with the TX output power and frequency channel setting. The determined VCC2 setting is also used to set the VCC2 supply voltage for the power amplifier. Once set, VCC2 remains fixed until the next request. Each individual handset uses this Adaptive Average Power Tracking (AAPT) method, thereby reducing its VCC2 voltage during operation and conserving power. Because each handset uses AAPT, factory calibration to account for unit-to-unit variations in transmitter circuitry performance is avoided.

Some embodiments of the present invention provide a system that computes a target secret St in a sequence of secrets S0 . . . Sn. During operation, the system obtains k hash functions h1, . . . , hk, where h1 is known as the “lowest order hash function”, and hk is known as the “highest order hash function.” Associated with each hash function hi is a seed value seed comprising a pair (seedindexi, seedvaluei). Hash function hi operates on a pair (indexi, valuei) to produce a pair (newindexi, newvaluei), where newindexi>indexi. To compute target secret St, the hash functions are applied successively, starting with the highest order hash function whose associated seed's index value is largest without being greater than t, applying that hash function as many times as possible without having that hash function's output's index value become greater than t, and then applying each successive hash function in turn as many times as possible, until St has been computed. To delete the earliest computable secret in the chain, S1, the new seed for each of the hash functions is computed as follows. Let x=1+index1, (the index of the seed associated with the lowest order hash function). For each hash function hi, if x>indexi, then hi is applied to seedi. If the resulting indexi is greater than indexi+1, then (indexi+1, valuei+1) associated with hashi+1 is copied into the (index, value) associated with hashi. Otherwise, seed is replaced by hi(seedi).

One example embodiment may calculate an adaptive clamp threshold for each pixel in the image data. Another example embodiment may calculate an adaptive clamp threshold for each pixel in a row of pixels in the image data.

A controller for vector-controlled motor of vehicle judges whether a battery needs to be warmed up in accordance with an output of a battery temperature sensor, and when the battery needs to be warmed up, in situation (i) where the vehicle is stopped, sets a q-axis current value of the motor at zero, or when a brake is released from the situation (i), sets a q-axis current at a value corresponding to a drive torque for a vehicle creep operation, and sets a d-axis current at a value for battery warm-up. When the battery needs to be warmed up in situation (ii) where the vehicle is running, the controller sets a q-axis current at a value corresponding to a drive torque of vehicle running and sets a d-axis current at a value for the battery warm-up in relation to the q-axis current value.
