The present invention relates to a compression device for stimulating the efflux of a body fluid from a body part. The device has a compression unit with a pressure-application region made of a deformable material, the region being formed to generate a repulsive force between the body part and the compression unit. The repulsive force passes through a force maximum then decreases to serve as an indication that the body part is guided sufficiently firmly and far enough onto the compression unit.

A syringe for use with a powered injector to inject a fluid into a patient that includes a length of material adapted to transmit or propagate electromagnetic energy therethrough. The length of material includes at least a first indicator positioned along the length of material. The first indicator is adapted to interact with at least a portion of the energy being propagated through the length of material in a manner that is detectable. The presence (or absence) of the first indicator provides or corresponds to information about the syringe configuration. The indicator(s) of the present invention can, for example, provide information about syringe configuration by the number and / or position thereof. A plurality or set of such syringes can be provided, with the configuration of each such syringe being represented by the presence or absence of indicator(s) of that syringe.

A business form particularly adapted for use in a medical or hospital environment includes in a first embodiment a wristband assembly that is readily separable from a carrier comprised of a layer of face stock and a laminate, with the wristband including a printable face stock region die cut into the face stock and a strap portion, a laminating portion, and a cinch die cut into the laminate layer. The laminating portion includes two halves which fold together about a fold line to enclose the face stock, with the strap portion extending from one of said halves. The cinch may be located in one of two locations, either in an extension from the other side of the face stock or intermediate the face stock and the strap portion. In either case the cinch comprises a slot through which the strap portion is inserted and then adhered to itself after its length has been adjusted by the medical professional. If an extension is provided, it may be folded over to adhere to the strap portion and clamp it in place there as well as being adhered at its end back onto itself, as described. An extender is also described which includes a clamshell joinder and a tail portion. The clamshell portion may be applied to the strap portion anywhere along its length to extend the effective length of the strap portion. Any of the wristband constructions may be provided on a page sized sheet along with a plurality of self adhering labels, in any of a number of configurations, to suit any particular application, as desired by a user.

A vacuum system for machine shop dust, particulate matter, and the like. Blast gates control the flow of vacuum generated by a dust collector to individual machines that may or may not accommodate vacuum ductwork and the like. The blast gate has a rotating blade inside a chassis with a DC motor effectively using a slip clutch or an increased current feedback system to limit the rotation driving of the rotating blade. Importantly, a small aperture serves to allow air flow into the chassis gap through which the rotating blade rotates in order to ensure the particular matter does not lodge inside the chassis thereby preventing the proper operation of the rotating blade. A central controller having a microprocessor or the like may be programmed or programmable and serve to individually control a selected number of blast gates based upon a feedback mechanism. A piezoelectric sensor or the like senses the vibration arising from the turning on of the associated machinery, indicating the demand for vacuum power to collect particulate matter. In response to the piezoelectric sensor's signal, the blast gate is opened and the dust collector is either turned on or stepped up to accommodate the increase load upon the vacuum system. The reverse situation occurs when the machinery is turned off. The piezoelectric sensor ceases signalling the central controller of the machine "on" condition. The central controller then steps down the dust collector / vacuum system and closes the associated blast gate. Alternative embodiments are set forth whereby additional features provide for enhanced utility, including a computer operation, control, monitoring, and feedback.

A welding system includes an imaging system that takes frame by frame pictures of a weld puddle. The imaging system is located in the weld torch. From the images puddle length and width are determined. The length and width are applied against stored membership functions that cover a range of different weld current characteristics and the degree of membership of each dimension in those functions is determined, producing an alpha factor for each membership function. This provides a fuzzy current requirement. Stored values for moment and area for each membership function are multiplied by the alpha for the respective function. The total of the moments is divided by the total of the areas to produce a desired weld current. The weld head includes a weld wire feeder that is driven by a servo by which the wire can be feed along either side of the weld joint. The wire feeder is gear driven in such a way that it does not interfere with the optics in the weld torch. The optics include a strobe to illuminate the puddle. Signal processing includes a process for interpolating the puddle centerline from the range in puddle widths over successive strobed images of the puddle. The head is positioned automatically over the centerline.

A transmitter is provided having transmission methods that minimize the power needed to ensure reliable reception in a coverage area. In one aspect, data that requires re-transmission as acknowledged mode data is re-transmitted when the power level of the transmission link is higher than a pre-determined level set for reliable reception. The data rate of the re-transmitted data is set according to the difference in the actual power and the pre-determined level. In a second aspect, two transmitting antennae are used to transmit the same signals with a frequency off-set. The frequency off-set can be used to determine the phase of the signals being received at the receiver, so that a phase off-set can be introduced to optimise the effect of interference at the receiver.

An ultrasonic detector (10) suitable for mounting in a position for surveying an area for a source of airborne ultrasound, which detector comprises a sensor (20) for detecting an ultrasonic sound signal, characterised by a transducer (64) configured to produce a broadband ultrasonic sound signal for reception by said sensor (20) enabling said ultrasonic detector to perform a self-test.

A system and apparatus are disclosed including PV modules having a frame allowing quick and easy assembling of the PV modules into a PV array in a sturdy and durable manner. In examples of the present technology, the PV modules may have a grooved frame where the groove is provided at an angle with respect to a planar surface of the modules. Various couplings may engage within the groove to assemble the PV modules into the PV array with a pivot-fit connection. Further examples of the present technology operate with PV modules having frames without grooves, or with PV modules where the frame is omitted altogether.
