Abstract: A medical cart is provided for use in patient care, the medical cart comprising: a front; a back; sides; four legs which have a distal end, a proximal end and a bore at least partially therebetween terminating in an aperture at the proximal end; an accessory pole releasably retained in the bore; a bracket attached to each leg proximate to the distal end; a caster rotatably attached to each bracket with a caster mount; a lower shelf in engagement with the sides; an upper shelf retained by the sides and an asymmetric handle which defines a gap.

Abstract: A medical cart for use in patient care is provided, the medical cart comprising: a front; a back; sides; four legs which have a distal end, a proximal end and a bore at least partially therebetween terminating in an aperture at the proximal end; a spring plunger mounted on each leg for releasably retaining a pole in the bore; a bracket attached to each leg proximate to the distal end; a caster rotatably attached to each bracket; a lower shelf attached to the legs and extending between the legs; a ballast sleeve below the lower shelf for releasably retaining weight plates; and an upper shelf attached to the legs and extending between the legs, the upper shelf including a recess at the front extending towards the back.

Abstract: Methods of generating a write current in response to a write command include generating a reverse preshoot write current having a polarity opposite to a polarity for generating a magnetic transition corresponding to the write command, and then generating a write current to effect the magnetic transition corresponding to the write command. The write current may be used for writing data to a storage disk of a disk drive that includes a write head configured to apply a magnetic field to the storage disk responsive to write currents. A preamplifier circuit includes a write current generator configured to receive a write current command and configured to generate, responsive to the write current command, a reverse preshoot current having a first polarity that is opposite a second polarity for generating a magnetic transition corresponding to the write command.

Abstract: A disk drive includes a rotatable data storage disk, and head, a controller, and a preamplifier. The head is configured to write data to and read data from the disk. The controller is configured to generate a write current command. The preamplifier includes a plurality of write current parameters, and is configured to select among the plurality of write current parameters based on the write current command from the controller, and to generate a write current having a shape that varies based on which of the write current parameters are selected. The write current is provided to the head to write a plurality of data bits on the disk.

Abstract: A central processor unit (CPU) is capable of being connected in data processing systems having diverse logical operating characteristics. The CPU contains an operating mode register that has stages that identify various logical operating conditions in the data processing system, and modify the operation of the central processor unit in accordance therewith.
