A novel adjustable screed bar holder used to support screed bars used in concrete finish work. The holder moves along a supporting device such as a stake, pin, or post. A lever on the holder is coupled to a cam wheel such that movement of the lever will disengage the cam wheel from the stake. When the cam wheel is in the disengaged position the holder is free to move along the stake until the lever is released and the cam wheel secures against the stake. Typically the holder will be used to hold a piece of lumber, pipe, rebar, or tubing parallel to the forms used in concrete placement. A screed may then be run over the concrete while it rides on the screed bar supported by the adjustable holder.

A glucose sensor assembly useful in patient systems includes an oxygen sensor from which glucose levels in the vicinity of the peritoneal cavity may be inferred. The sensor assembly may be associated with electronics, such as any or all of a DC power supply, an LED source of blue light, a photoreceptor for red light, a CPU, and transceiver, by a direct percutaneous connection. Alternatively they may be associated transdermally with the sensor and some of the electronics being located subdurally. Insulin infusion means are contemplated to respond manually or mechanically to information from the sensors through the CPU. Mechanical response may be automatic. Infusion means may be located subdurally. It is contemplated that the present invention enable revitalization or replacement of fluorescing compounds and glucose oxidase within the sensor assembly.

An apparatus and method for controlling the current delivered to a flash lamp is disclosed. The apparatus and method is particularly useful for controlling the current delivered to a flash lamp used in a laser and most particularly useful in connection with lasers used for medical procedures. The apparatus controls the length of the electrical pulse which is delivered to the flash lamp and also limits the current which passes through the flash lamp to that which is desired for optimized operation. A semiconductor switch electrically connects and disconnects the flash lamp from one or more capacitors for the desired length of time. The length of time can be automatically adjusted to provide the desired flash lamp output and thus the desired laser output. The switch provides substantially a square wave having a plateau voltage with very fast rise and fall times on both sides of the plateau so that a suitable square wave is formed. The semiconductor switch also limits the value of the current passing through the flash lamp to a substantially predetermined value so that the operation of the lamp is optimized.
