This invention provides devices, compositions and methods for determining the concentration of one or more metabolites or analytes in a biological sample, including cells, tissues, organs, organisms, and biological fluids. In particular, this invention provides materials, apparatuses, and methods for several non-invasive techniques for the determination of in vivo blood glucose concentration levels based upon the in vivo measurement of one or more biologically active molecules found in skin.

The electromagnetic shield is disposed proximate to the sensor die. The electromagnetic shield has at least one feature selected to reduce an eddy current in the electromagnetic shield

A wireless network device (4), such as a wireless media centre, has orthogonally polarised antennas (6a, 6b) arranged to provide transmit and / or receive polarisation diversity. The antennas may be arranged so that their nulls do not coincide, to produce a combined antenna pattern with a low variation of gain with direction. The antennas may be collocated, but arranged orthogonally. Preferably, the combined antenna pattern is substantially omnidirectional in elevation as well as azimuth. This arrangement provides uniform coverage in a 3D environment. The transmitter may transmit data using polarisation-time block codes. A wireless receiver (10, 18) for use in the wireless network may have either one antenna or two orthogonally polarised antennas. The receiver (10, 18) applies maximal ratio combining to the received signals. The signals may be OFDM signals and the receiver applies maximal ratio combining independently to each frequency channel. The antennas may be flat linear or annular slot antennas, which provide strongly polarised beams and can be integrated within the housing of the devices.

A thermally compensated circuit breaker has a movable contact assembly (24) which mounts a movable electrical contact (24m) for movement between open and closed contacts positions with a stationary electrical contact (26). The contacts are maintained in the closed circuits position by a latching mechanism (24b, 28g) which prevents opening of the contacts through an opening contacts force provided by a spring (24e). A current carrying trip arm (40a, 44a) deflects upon sufficient I.sup.2 R heating to transfer motion to the latch to separate the latch (24b) from the latch receiving catch (28g) to trip the circuit breaker. The trip arm (40a, 44a) is part of a pivotably mounted actuator assembly (40, 44) having a movable end portion spaced from the pivot disposed adjacent a motion transfer member (28c). A calibration screw (42a) is located so that the longitudinal axis is in line with a movable end portion of the actuator assembly and the motion transfer member. In one embodiment the head of the calibration screw is captured in a slot in the free end of a calibration base (42d) attached to the trip arm so that deflection of the trip arm directly transfers motion to the motion transfer member and in another embodiment the calibration screw head is captured in a slot in the free end of the trip arm so that a bowing deflection of the trip arm causes a calibration base (46) to which it is attached at an end thereof to rotate with the calibration base directly transferring motion to the motion transfer member.

A mouthpiece that adjusts manually to accommodate a broad range of different size sets of upper and lower teeth in the mouth and yet seals the treatment area from oxygen exposure. The mouthpiece includes light emitting diodes and heat generating resistors all arranged in an array. A series of parallel texture bands are provides to guide and direct the light from the LEDs to diffuse generally evenly onto teeth to be treated. The seal arises from an inner surface of the mouthpiece titling inwardly so that a seal bead seals in the vicinity of the gum above the teeth to be treated.

Disclosed is an inkjet print cartridge including an ink supply, a substrate having a plurality of individual ink ejection chambers defined by a barrier layer formed on a first surface of the substrate and having an ink ejection element in each of the ink ejection chambers, for ejecting drops of ink having a predetermined drop volume and drop velocity. The ink ejection chambers each have the same inlet channel length and are arranged in an array spaced so as to provide a predetermined resolution. A nozzle member having a plurality of ink orifices formed therein is positioned to overlie the barrier layer with the orifices aligned with the ink ejection chambers. An ink channel connects the reservoir with the ink ejection chambers. The inkjet print cartridge has several advantages of over previous printing systems in creating high quality images by using very small individual ink drops of low volume and high velocity. Highlight regions may be formed by using single low volume drops to form a dot. The individual drops are nearly invisible and can be used to form highlights with low graininess. As the density of the image increases, multi-drop dots are formed from two or more drops merging on the media to form a composite drop.

Inductive position sensors and circuit configurations are disclosed for the measurement of linear, rotary, or curved position along a motion axis. The simplified sensor structures combine one or two parts of a movable core element with a simple planar substrate having first and second inductances connected in series. Movement of the core element in parallel to the planar substrate causing the impedance of at least one of the inductances to change. Simple circuit configurations are taught by which the impedance change is converted into a useful output signal that indicates position along the motion axis.

An implantable medical lead for stimulation of the sacral nerves comprises a lead body which includes a distal end and a proximal end, and the distal end having at least one electrode contact extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. The electrode contact of the permanently implantable neurostimulation lead comprises an elongated, flexible, coiled wire or mesh electrode having an exposed electrode length that is adapted to be inserted through the foramen from a posterior access to locate the coiled wire electrode alongside the sacral nerve extending anteriorly and / or posteriorly therefrom. The coiled wire or mesh electrode structure is flexible and bendable to enable its placement through the foramen and alongside the sacral nerve and to conform to the surrounding nerves and tissue. Preferably, further shorter length electrodes are provided along the distal segment of the lead body to enable testing of the positioning of the elongated wire coil or mesh electrode or to provide alternate stimulation electrodes upon dislocation of the elongated wire coil or mesh electrode.

A performance monitoring method for an optically amplified transmission system. The method provides the optical power at each amplifier site, taking into account the inaccuracies introduced by the SRS in the power estimation obtained with the current methods. An optical spectrum analyzer is used at the output of the transmission link of interest to accurately measure the output power of each wavelength. This value is sent upstream to the last amplifier in the link, to compute an error term as the difference between the actual measurement and the estimation. The error term is used to infer the SRS-induced error by system elements not accounted for in the model. The error term is then fed-back to each amplifier in the link, so that the estimated power is adjusted to account for the SRS-induced inaccuracy.
