Abstract: The invention provides a method of electrical artefact compensation in measurement of a neural response. The neural response is evoked by a first stimulus, after which a compensatory stimulus is applied in order to counteract a stimulus artefact caused by the first stimulus. The invention also provides for short circuiting the stimulating electrode subsequent to the first stimulus. A system for implementing such steps is also provided. The invention may be of application in measurement of physiological responses, including neural responses and in particular a neural response of the auditory nerve.

Abstract: A low-power, high-dynamic range, analog-to-digital (A/D) conversion circuit for converting an analog signal to a digital signal having a controllable amplifier for amplifying the analog log signal received at an input of the amplifier in response to a first control signal and for generating an amplified analog signal, a low dynamic range A/D converter for converting the amplified analog signal to an intermediary digital signal, a controllable bit shift register for scaling the intermediary digital signal in response to a second control signal to generate the digital signal, and a gain control component (AGC) for generating the first control signal to cause the amplified analog signal to be within the dynamic range of the A/D converter and for generating the second control signal to cause the scaling to compensate for the amplification by the amplifier.

Abstract: A method and device for measuring an evoked neural response comprising a sensor (25) for obtaining a sensed signal representing the evoked neural response, a high gain amplifier (30) having a signal input (31) for receiving the sensed signal and having a reference input (32), and means for altering or setting a reference voltage at the reference input (32) to prevent the amplifier (30) saturating with variations of the sensed signal.

Abstract: A flexible polymeric container for holding albumin. The container is made of a sheet of flexible polymeric film formed into a bag having a cavity enclosed by a first wall, an opposing second wall, and seals about a periphery of the first and second walls. The seals join an interior portion of the opposing first and second walls and create a fluid-tight chamber within the cavity of the container for storing a concentration of the albumin.

The container is made of a sheet of flexible polymeric film formed into a bag having a cavity enclosed by a first wall, an opposing second wall, and seals about a periphery of the first and second walls. The seals join an interior portion of the opposing first and second walls and create a fluid-tight chamber within the cavity of the container for storing a concentration of the albumin. A method of packaging the albumin protein into a flexible polymeric container is also provided. Therein a flexible polymeric material is converted into bags, the bags are filled with a quantity of albumin by a filler, and a seal area of the bags is sealed to enclose the albumin within the bag.

Abstract: There is disclosed a syringe assembly for the storage and application of a biological multi-component material. Its assembly parts are a syringe device including several parallel syringe bodies interconnected by a connection part, which syringe bodies are filled with the individual components of the multi-component material, include coni and are closed by pistons; an actuation device for this syringe device, which includes piston rods associated with the pistons and a common grip element; and a dispensing element to be attached to the coni of the syringe bodies. The filled syringe bodies, which are closed by separate piston plugs, constitute a one-piece syringe unit with the connection part. The connection part leaves a recess between the syringe bodies on one of the ends of the syringe unit for receiving a protection means shielding off the other syringe body/ies when filling the syringe bodies.

Abstract: A guard grid is used as protection in a ventilating shaft and similar passageways in structures with a considerable wall thickness, and the guard grid is particularly useful in nuclear power stations. In the passageway direction, the guard grid is divided into a number of grid-like members one following the other. The grid-like member on the outside of the structure has crossbars extending between opposite sides of the passageway and spacer bars extending perpendicularly to the crossbars. The crossbars and spacer bars form a honeycomb-like structure with a dimension in the direction of the passageway equal at least to the dimension of the spacer bars extending transversely of the passageway direction.

Abstract: In an office machine with an electric drive motor which is arranged in a machine well and on the one shaft end of which an axial blower wheel is fastened to blow a stream of cooling air from an opening in the well in the vicinity of the one end of the motor, an external blower wheel is provided at the motor end facing away from the machine well opening outside the end bell of the motor and the axial blower wheel and the motor are surrounded by an air duct housing partly defined by the machine well and partly by a separate air baffle, in such a way that the air stream is conducted over the motor to the machine well opening to obtain forced surface ventilation.
