A vehicle bicycle rack is provided including a telescopic, height-adjustable support, attachable to a vehicle, and an arm assembly carried by the support for holding one or more bicycles. The arm assembly is pivotably mounted to the support and is height-adjustable by adjusting the height of the support. The arm assembly can adopt various rotational positions, including a stowed position in which the arm assembly is pivoted downward, and a deployed position in which the arm assembly is pivoted rearward and one or more bicycles can be carried by the arm assembly.

Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight and whether the container weight is below a pre-established threshold, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.

A system and method are described involving the use of a cell delivery catheter that incorporates a stimulating electrode to promote vasodilation prior to injection of cells at a target location within a blood vessel. The vasodilation may be produced locally and/or distally from the target location near the target organ. The technique may be applied not only to intra-coronary injection of cells to treat heart disease but to injection of cells in any blood vessel that feeds a target organ.

An exercise equipment pack is adapted to assist a user in performing one or more exercises. The equipment pack includes a base frame. The base frame includes: a front substantially-cylindrical canister portion, formed integrally with the base frame and projecting therefrom; a rear substantially-cylindrical canister portion, formed integrally with the base frame, and projecting therefrom in a direction opposite from the front canister portion; and a common wall, formed integrally with the base frame and forming a common inner base surface for both the front canister portion and the rear canister portion, the common wall having an opening. The front canister portion, the rear canister portion and the common wall together forming a cylindrical storage area divided by the common wall, the cylindrical storage area being adapted to securely maintain one or more weights on each side of the common wall.
摘要:
A thin film of white blood cells is irradiated with ultraviolet radiation predominately of a wavelength of 280 to 320 nanometers, and preferably at an intensity of 4 to 15 milliwatts per square cm. At such a radiation intensity it is not necessary to agitate the thin film of white blood cells to accomplish the purposes of this invention. The white blood cells so processed substantially lose their capability to set off an immune reaction in an alloimmunized patient. The white blood cells may preferably be placed into such film in a flat, flexible bag made of poly(ethylene-vinyl acetate) plastic, with the flat, flexible bag being stretched in a direction normal to the path of ultraviolet radiation.

摘要:
Air bubbles may be characterized by an air bubble detector by choosing an optimum set of frequencies and then comparing a return signal from a sensor receiving those frequencies against an internal reference. The number of pulses that exceed the internal reference represents a width and may be counted. The width, as counted, may be correlated to bubble characteristics including volume.
摘要:
A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.
摘要:
A method and system is provided that in a fully automated manner notifies users of price conditions, including both conditions set by the user and conditions determined to be of interest to the user. An exemplary method according to the invention is a method for online consumer price alerts in which a request is received from the user to notify the user when the price of a product reaches a specific price threshold. The price of the product is monitored on a plurality of merchant web sites, and a notification is provided to the user when the price of the product is at or below the specific price threshold.
摘要:
