摘要:
A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. All frequency components of the magnetic field are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters. In one embodiment, a sensor having a core, preferably ferrite, which is curved, such as in a U-shape or in the shape of a section of a torus, and defining a gap, is provided with a wire winding for excitation and/or detection. The sensor can be used for simultaneously obtaining data relating to two or more parameters of a coin or other object, such as size and conductivity of the object. Two or more frequencies can be used to sense core and/or cladding properties. Objects recognized as acceptable coins, using the sensor data, are diverted by a controllable deflecting door, to tubes for delivery to acceptable coin bins.

A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.

A percutaneous electrical therapy system includes sharp point protection. In one embodiment, the system includes a control unit; an electrode assembly adapted to deliver electrical therapy to a patient, where the electrode assembly has an electrode electrically connectable to the control unit, the electrode having a sharp point at a distal end adapted to be inserted into the patient's tissue; and a sharp point protection assembly operable with the electrode assembly for reducing the risk of unintended exposure to the electrode's point. The system can also include an electrode assembly and sharp point protection assembly for a percutaneous electrical therapy system, as described above, apart from the control unit. In another embodiment, a method of performing percutaneous electrical therapy can include providing an electrode assembly having an electrode, the electrode having a sharp point at a distal end; inserting the sharp point of the electrode into a patient's tissue without exposing the sharp point to anyone but the patient; and applying an electrical signal to the electrode from a control unit.

In a preferred embodiment, a percutaneous electrical therapy system includes a control unit; an electrode electrically connected to the control unit to deliver electrical therapy to a patient, the electrode comprising a sharp point at a distal end adapted to be inserted into a patient's tissue at an electrode insertion point; and an electrode insertion pain reducer adapted to reduce pain experienced by the patient during insertion of the electrode into the patient's tissue. Both the electrode and electrode insertion pain reducer may be located apart from the control unit.
摘要:
The present invention describes a spatial addressing technique that uses a very high-density micro-pore array for high-throughput screening of biological interactions. The therapeutic, diagnostic and drug-discovery implications of being able to identify, select and characterize specific protein-protein, protein-DNA and/or protein-carbohydrate interactions from heterogeneous populations of millions (to billions) of cells is discussed. Importantly, this technique possesses the screening and selection capacity of current display-based screening systems (i.e., millions-billions) but with greater efficiency and shorter time.
