  • Patent number: 11726914
    Abstract: Methods, systems, and devices for bias control for a memory device are described. A memory system may store indication of whether data is coherent. In some examples, the indication may be stored as metadata, where a first value indicates that the data is not coherent and a second value or a third value indicate that the data is coherent. When a processing unit or other component of the memory system processes a command to access data, the memory system may operate according to a device bias mode when the indication is the first value, and according to a host bias mode when the indication is the second value or the third value.

  • Publication number: 20060177292
    Abstract: A high-clearance dump system is described for use with a riding mower. A folding lift assembly lifts the catcher box up and away from the riding mower to allow dumping over and away from the walls of a truck or other receiving vehicle. The folding lift assembly interfolds into the dumping catcher assembly and the dump system mount assembly thus providing a low-profile when in the lowered position. A lift pivot arm, and lift control rods that are shorter than the lift pivot arm, cause the catcher frame to be tilted at an obtuse angle with respect to the lift pivot arm so that the back end of the catcher frame is higher than the front end of the catcher frame when the lift pivot arm is raised, thus providing high clearance. A power system provides power a switch box that switches power between a lift cylinder and a dump cylinder so that the catcher may be dumped in a raised, partially raised, or lowered position.

  • Publication number: 20050083921
    Abstract: Instead of alternatively utilizing only one fabric or the other fabric of a redundant pair, both fabrics simultaneously transmit duplicate information, such that each packet forwarding module (PFM) receives the output of both fabrics simultaneously. In real time, an internal optics module (IOM) analyzes each information chunk coming out of a working zero switch fabric; simultaneously examines a parallel output of a working one duplicate switch fabric; and compares on a chunk-by-chunk basis the validity of each and every chunk from both switch fabrics. The IOM does this by examining forward error correction (FEC) check symbols encapsulated into each chunk. FEC check symbols allow correcting a predetermined number of bit errors within a chunk. If the chunk cannot be corrected, then the IOM provides indication to all PFMs downstream that the chunk is defective. Under such conditions, the PFMs select a chunk from the non-defective switch fabric.

  • Publication number: 20050011683
    Abstract: Disclosed is a self propelled walk behind mower comprised of a tractor unit and a mowing deck. The tractor unit is hydrostatically driven with a unique control system whereby the forward speed of the tractor is set by operating an electric rocker switch with an operator's thumb. Hand levers are used to turn the tractor to the left and the right. The tractor unit comprises two drive wheels and a third wheel that is pivotally attached, letting the tractor unit stand upright when no implements are attached. Implements attach to the front of the tractor through a movable attachment so that the tractor and implement can closely follow the contour of the ground while keeping the operator controls in a convenient position.

  • Patent number: 5692490
    Abstract: An archery release is provided utilizing ball bearings in the fulcrum or centerline of the drawing or pulling force. The release rotates about the bearing centerline to disengage a sear mechanism, thereby releasing a bowstring from a loop of cord connected to the sear mechanism.
