A blood pump system includes a first implantable housing, an implantable blood pump independent from the first implantable housing, and a percutaneous extension. The first implantable housing includes a rechargeable power storage device. The implantable blood pump supplements the pumping function of a heart. The rechargeable power storage device supplies electrical power to the implantable blood pump. The percutaneous extension is coupled to the rechargeable power storage device and adapted to traverse the skin. The percutaneous extension is configured to releasably connect to an external power supply adapted to provide power for recharging or supplementing the rechargeable power storage device to power the implantable blood pump.

An information-processing apparatus determines whether a stimulation generation unit and a background virtual object contact each other based on position and orientation information about the stimulation generation unit and position and orientation information about the background virtual object. If it is determined that the stimulation generation unit and the background virtual object contact each other, the information-processing apparatus determines whether the stimulation generation unit is included within an attention range. The information-processing apparatus generates operation setting information for controlling an operation of the stimulation generation unit according to a result of the determination and outputs the generated operation setting information to the stimulation generation unit.

In order to produce a pulsatile blood flow pattern that includes time periods of relatively high blood flow rates and time periods of relatively low blood flow rates, the operating speed of a blood pump can be selectively controlled to produce an operating speed pattern that includes time periods of relatively high rotation speeds and periods of relatively low rotation speeds For example, the blood pump is rotated at a first speed for a first period of time The speed of the blood pump is then decreased from the first speed to a second speed and is operated at the second speed for a second amount of time The speed of the blood pump is then decreased to a third speed for a third amount of time If desired, the operating speed pattern can be repeated to continue the pulsatile blood flow pattern

A teleoperated robotic system that includes master control arms, slave arms, and a mobile platform. In use, a user manipulates the master control arms to control movement of the slave arms. The teleoperated robotic system can include two master control arms and two slave arms. The master control arms and the slave arms can be mounted on the platform. The platform can provide support for the master control arms and for a teleoperator, or user, of the robotic system. Thus, a mobile platform can allow the robotic system to be moved from place to place to locate the slave arms in a position for use. Additionally, the user can be positioned on the platform, such that the user can see and hear, directly, the slave arms and the workspace in which the slave arms operate.

Teleoperated robotic system

Featured is a controller for a motor that is ultra-compact, with a power density of at least about 20 watts per cubic cm (W/cm 3 ). The controller utilizes a common ground for power circuitry, which energizes the windings of the motor, and the signal circuitry, which controls this energization responsive to signals from one or more sensors. Also, the ground is held at a stable potential without galvanic isolation. The circuits, their components and connectors are sized and located to minimize their inductance and heat is dissipated by conduction to the controller's exterior such as by a thermally conductive and electrically insulating material (e.g., potable epoxy). The controller uses a single current sensor for plural windings and preferably a single heat sensor within the controller. The body of the controller can also function as the sole plug connector.

A robotic device (10) has a base and at least one finger (46a-c) having at least two links that are connected in series on rotary joints (32a,b) with at least two degrees of freedom. A brushless motor and an associated controller are located at each joint to produce a rotational movement of a link. Wires for electrical power and communication serially connect the controllers in a distributed control network. A network operating controller coordinates the operation of the network, including power distribution. At least one, but more typically two to five, wires interconnect all the controllers through one or more joints. Motor sensors and external world sensors monitor operating parameters of the robotic hand. The electrical signal output of the sensors can be input anywhere on the distributed control network. V-grooves on the robotic hand locate objects precisely and assist in gripping. The hand is sealed, immersible and has electrical connections through the rotary joints for anodizing in a single dunk without masking. In various forms, this intelligent, self-contained, dexterous hand, or combinations of such hands, can perform a wide variety of object gripping and manipulating tasks, as well as locomotion and combinations of locomotion and gripping.
