Abstract: Charge storage devices (e.g., batteries or supercapacitors) need to be charged from time to time. In an apparatus, to protect a charge storage device as well as the supply used to charge it, the apparatus typically includes power loop control circuitry. One approach to implementing the power loop control employs a temperature sensor in combination with soft start circuitry in order to protect the circuitry from a rapidly increasing temperature when charge current increases. The soft start circuitry allows for controlled step-wise increase and regulation of the current. The approach preferably allows for selecting the number and resolution of such incremental steps. Various embodiments of the invention include devices and methods for controlling power and may take into account temperature in step-wise regulation of the charge current.

Abstract: Techniques for generating cyclic redundancy check (CRC) values are provided. Bit messages that are to be transmitted to recipients are aligned to desired byte boundaries for purposes of generating CRC values, which are to be sent with the bit messages. The CRC values are rewound or adjusted back to values associated with original lengths of the bit messages before the CRC values are transmitted or forwarded with the bit messages to recipients.

Abstract: A method for performing a synchronized order change in a manufacturing process is provided. An order is associated with an order number and a work in process (WIP) number, which identifies a physical lot corresponding to the order. The synchronized order change maintains a relationship between the order number and the WIP number while making the change. This avoids the need to scrap lots that are no longer associated with an order number and prevents holds from being placed on incorrect lots.
