International Classification:

B67C 1100

US Classification:

141 86, 141341

Abstract:

A oil drainage re-directing device for preventing oil from dripping on a U-joint when an oil filter is removed. The oil drainage re-directing device includes a panel having a top surface, a bottom surface, a back edge, a front edge, a first side edge and a second side edge. The panel is divided into a left portion and a right portion along a longitudinal axis of the panel. The left portion is in an angular relationship with the right portion such that the top surface of the panel defines an angle generally between 120 degrees and 150 degrees. The panel comprises a substantially rigid material. A foot is attached to the bottom surface of the panel and is positioned generally between the front and back edges. The panel is positioned on a U-joint of a vehicle and under an oil-filter for preventing oil from falling on the oil-filter when the oil filter is removed.

Abstract:

Disclosed is a technique for storing a count of incrementally increasing data exclusively in EEPROM using semaphores to avoid significant losses, as a result of power downs, greater than a single least significant bit in accuracy. The disclosed embodiment includes a first EEPROM register, comprised of 256 bits, for storing 256 incremental count increases, each bit is used to record an incremental count increase. A pair of 16 bit EEPROM registers is provided for incrementally storing updated count information in response to the first EEPROM register overflowing. Semaphores are provided for indicating whether or not the incrementally increasing count information has been at least partially stored in the pair of registers. Once an overflow from the first register is detected, the semaphores are checked to determine in what stage the update to the pair of registers was left (in case of power down). In response to the semaphore information, the overflow is stored in the pair of registers for a complete update of the count, and the semaphores are appropriately updated to so indicate.
