An improvement is described to disposable devices for performing chemical or biological tests on a sample of fluid, and the method by which such devices perform tests. The power for the device comes from an electrochemical battery, where a portion of the fluid sample itself provides the electrolyte for the battery. Furthermore, the time of diffusion of the fluid into the battery provides the timing signal for activation of the system. Communication between the improved device and an information system is provided by a transponder system built into the device which requires no direct electrical connection. Rather, the device is placed in proximity with a reader which can interrogate the device, obtain the results of the test and if necessary provide power for the device to perform the test, and / or communicate the information. The improvements and methods are particularly applicable to devices for performing in vitro diagnostic tests on a sample of body fluid.

Techniques for reducing the complexity and improving the accuracy of receive signal strength based location systems. The system comprises a plurality of radio sensor devices placed at known positions within a space in which devices are to be located. According to one technique, the path loss is measured between all combinations of pairs of radio sensor devices based on a test signal transmitted by each radio sensor device. A path loss model is evaluated to compute modeled path loss data between all combinations of pairs of radio sensor devices. For each measured path loss, a path loss error relative to each radio sensor device is computed by taking the difference between the measured path loss and the modeled path loss. The path loss error relative to each radio sensor device at any candidate position is interpolated from the computed path loss errors. A path loss estimate between a candidate position and each radio sensor device is computed by adding the interpolated path loss error relative to that radio sensor device at the candidate position and path loss data obtained by evaluating the path loss model based on the distance between at each candidate position and the corresponding radio sensor device. When determining the position of a device emitting radio signals (called a target device), the improved path loss estimate is used. According to another technique, for each radio sensor device, parameters are derived for a path loss model function from the measured path loss between that radio sensor device and each of the other radio sensor devices using a minimization computation. Then, a path loss estimate between a position and each radio sensor device is computed by evaluating the path loss model function using the parameters derived for each radio sensor device.

An automated system and method of geometric 3D point location. The invention teaches a system design for translating a CAD model into real spatial locations at a construction site, interior environment, or other workspace. Specified points are materialized by intersecting two visible pencil light beams there, each beam under the control of its own robotic ray-steering beam source. Practicability requires each beam source to know its precise location and rotational orientation in the CAD-based coordinate system. As an enabling sub-invention, therefore, an automated system and method for self-location and self-orientation of a polar-angle-sensing device is specified, based on its observation of three (3) known reference points. Two such devices, under the control of a handheld unit downloaded with the CAD model or pointlist, are sufficient to orchestrate the arbitrary point location of the invention, by the following method: Three CAD-specified reference points are optically defined by emplacing a spot retroreflector at each. The user then situates the two beam source devices at unspecified locations and orientations. The user then trains each beam source on each reference point, enabling the beam source to compute its location and orientation, using the algorithm of the sub-invention. The user then may select a CAD-specified design point using the handheld controller, and in response, the handheld instructs the two beam sources to radiate toward the currently selected point P. Each beam source independently transforms P into a direction vector from self, applies a 3×3 matrix rotator that corrects for its arbitrary rotational orientation, and instructs its robotics to assume the resultant beam direction. In consummation of the inventive thread, the pair of light beams form an intersection at the specified point P, giving the worker visual cues to precisely position materials there. This design posits significant ease-of-use advantages over construction point location using a single-beam total station. The invention locates the point effortlessly and with dispatch compared to the total station method of iterative manual search maneuvering a prism into place. Speed enables building features on top of point location, such as metered plumb and edge traversal, and graphical point selection. The invention eliminates the need for a receiving device to occupy space at the specified point, leaving it free to be occupied by building materials. The invention's beam intersection creates a pattern of instantaneous visual feedback signifying correct emplacement of such building materials. Unlike surveying instruments, the invention's freedom to situate its two ray-steering devices at arbitrary locations and orientations, and its reliance instead on the staking of 3 reference points, eliminates the need for specialized surveying skill to set up and operate the system, widening access to builders, engineers, and craftspeople.

A support which positions a musical instrument or other device in front of a musician or user in a near-vertical orientation, while comfortably distributing the instrument's weight upon the musician's body. It comprises a strap made from a strip of flexible material which is passed over the shoulder of a musician. The ends are attached to a guitar at points of attachment located upon either side of the guitar's body, a departure from previous practice. Due to the selection of the points of attachment, the guitar is supported in a generally vertical orientation. The tuner head or upper portion of the guitar then extends to a position generally above the musician's shoulder. A shoulder pad of cushioning material is slidably affixed to the underside of the strap. An adjustable cord or strap is attached from the shoulder pad to the guitar's tuner head, whereby the cord can secure and stabilize the positioning of the tuner head and thus the vertical orientation of the guitar. In addition, upwardly-pulling tension afforded by the cord's attachment to the guitar's tuner head stabilizes the position of the shoulder strap at the highest point of the strap, which is above the musician's shoulder. The guitar is supported and positioned in a near-vertical position, and the musician can play freely with both hands, without requiring either hand for support or positioning of the instrument. Such positioning enhances certain musical techniques, including "two-handed tapping' or "touch-style' methods of play. The guitar will remain in the proper playing position during seated or standing performance and during performance gyrations, and the shoulder pad will remain properly positioned atop the musician's shoulder during a performance.
