Abstract: A blood pump for assisting a heart is provided having a stator and a rotor. The rotor is magnetically radially supported creating a suspension gap between the stator and the rotor. The rotor can be supported axially by a Lorentz force bearing and can be magnetically rotated. The stator can have a single or double volute pump chamber and the rotor can have an impeller portion for pumping blood. The rotor can have a center bore as a primary blood flowpath. The suspension gap can be a secondary blood flowpath. The blood pump can also have an axial position controller and a flow rate controller. The axial position controller can cause the axial bearing to adjust the position of the rotor. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A method of operating the flow rate controller to create a pulsatile flow rate is also provided. Additionally, the blood pump can be part of a cardiac assist and arrhythmia control system. Moreover, a method of operating the flow rate controller can be provided which reduces the amount of energy needed to treat fibrillation. The method can include operating the flow rate controller to reduce a radial dimension of the ventricle prior to delivering defibrillation energy such that the ventricle contains less blood which absorbs less energy so that a larger fraction of the energy is delivered to the heart.

Abstract: An ergonomic handgrip for use as a fitness grip and also for use with a wide variety of devices and equipment such as ski poles and bicycle handlebars by being incorporated into the handle portion thereof. In a basic illustrated form, the grip has an elongated base with a central axis and opposed ends, the upper of which ends includes a thumb support. The front face is sculptured or contoured for finger reception, so that, when gripped, the thumb is supported in a bent position and the hand and wrist are in a neutral position. In such neutral position the hand is not cocked or hyperextended, but rather the hand is generally aligned with the forearm. Further, the end of the base opposite the thumb support, i.e., the lower end, is reduced in size to allow disproportionately more contraction of the lowermost two fingers, and primarily the lowermost or little finger. When the grip is used as a standalone handgrip or when another element does not pass through the lower end thereof, the lower end includes a thickened inverted arcuate section having a central bore, the arcuate section being spaced in from the edges of the lower end. A preferred version includes an elongated recess within the base on the side directed toward the palm of the hand. The grip can also be employed by being incorporated into the handle or shaft of a hammer or mallet.

Filed: 1998-12-19
Granted: 2006-02-07
Abstract: A process and apparatus for converting an MPEG-2 bistream into an SMPTE-259 compatible bitstream are characterized by a frame rate converter which is selectively ambled to drop every 1001st frame of the incoming MPEG-2 bitstream depending on the input bitstream frame rate. If the input bitstream frame rate is other than 29.97 or 59.94 Hz, a frame dropper is enabled to discard every 1001st frame. The present converter can convert many different types of input bitstreams, such as all I types, IPIP types, or complex GOP types containing I, P, and B frames. The enabled frame dropper will drop either the I or P frame if it occurs as the 1001st frame, but if the 1001st frame is of the B frame type, the pixel information of the B frame is dropped. This produces a minimum in loss of information during the conversion. The format converter allows existing SMPTE-259 routing equipment to route and utilize MPEG-2 bitstreams, such as HDTV applications.

Abstract: Disclosed are network management procedures that apply measurements of traffic load to achieve greater efficiency in the operation of the network. In a method for deciding whether to route an incoming call on a selected potential service route, the potential service route is treated preferentially if each of its links has available capacity that is more than sufficient by a specified margin. In a method for computing billing revenues, the non-compliance of the network service provider with contracted requirements for carried load causes a revenue penalty to be exacted for lost bandwidth.

Abstract: To enable noise reduction control in a hydrostatic continuously variable transmission. A constant-displacement hydraulic pump and a variable- displacement hydraulic motor are disposed on the driving shaft, and are connected by a closed hydraulic circuit. Occurrence of hydraulic pressure on the hydraulic motor side is prevented by changing to TOP side the angle of the movable swash plate mounted on the hydraulic motor. When specific determining conditions are satisfied during engine operation, the movable swash plate of the hydraulic motor is inclined to TOP side, to prevent occurrence of an excess play between the rotating housing on the hydraulic pump side and the pump-side plunger, thereby reducing or preventing noise occurrence. The determining conditions are as follows. (1) The signal voltage of the throttle sensor 23 indicating the throttle opening is lower than the threshold value. (2) The vehicle speed is over the threshold value. (3) The acceleration is over the threshold value. (4) The engine speed is below the threshold value. (5) The establishment of conditions (1) to (4) is over a specific period of time.
