    摘要: A blood analysis apparatus for obtaining blood for analysis from the skin of a patient with a controlled degree of lancing. The apparatus including a cartridge and a driver. The cartridge includes a cartridge case and a lancet. The lancet has a tip and is housed in the cartridge case. The lancet can be driven to extend the tip outside the cartridge case through an opening for lancing the skin of the patient to yield blood. The driver drives the lancet to move the tip distally to lance the skin. The driver is triggerable by the skin which is to be lanced exerting a force exceeding a preset amount against the triggering mechanism of the apparatus, to drive the lancet toward the skin.

    摘要: A Z-axis backing layer for an acoustic transducer is provided, which comprises a matrix of electrical conductors disposed in parallel and potted within an electrically insulating acoustic backing material. The acoustic transducers are disposed on a first end of the backing layer, with each individual transducer element connecting electrically to a respective one of the conductors. At the other end of the backing layer, the conductors connect electrically to a corresponding circuit element. The backing layer is fabricated from a plurality of leadframes each having an outer frame member and a plurality of conductors extending in parallel across the leadframes terminating at the frame members at opposite ends thereof. The plurality of leadframes are stacked such that respective conductors of adjacent ones of the leadframes are disposed in parallel with a space provided between the respective conductors equivalent to a width of one of the leadframes. Acoustic backing material is poured onto the stacked plurality of leadframes to completely fill the spaces between conductors. The frame members and excess acoustic backing material are then removed from the stacked and poured plurality of leadframes.

    摘要: A transducer device and method include affixing a preamplifier or other suitable circuit to a thin piezoelectric membrane. The membrane fully supports the circuit at an inactive region of the membrane. The membrane has at least one piezoelectrically active region that is connected to the circuit by a signal line. Preferably, the signal line is fabricated onto the membrane using integrated circuit fabrication techniques. In the preferred embodiment, the piezoelectrically active region has a diameter of less than one hundred microns and the membrane has a thickness of less than ten microns. A potting compound provides structural support of the membrane and insulates the on-membrane circuit.

    摘要: A two-dimensional ultrasonic transducer array includes a plurality of transducer elements, with each element having a plurality of piezoelectric layers. The transducer elements vary in transverse areas of radiating regions. The effect of the variations in transverse areas on the electrical impedances of the elements is at least partially offset by varying the specific impedance, i.e., impedance per unit area, of the transducer elements in the array. In a preferred embodiment, the specific impedance is varied by selecting the electrical arrangements of piezoelectric layers in each element according to the transverse area of the element. Series, parallel and series-parallel arrangements are employed. This impedance normalization improves the electrical connection of the transducer elements to driving circuitry. In alternative embodiments, impedance normalization is achieved by varying element thicknesses, element materials and/or degrees of poling across the two-dimensional array.

    摘要: An acoustic device, such as a membrane hydrophone, includes a support structure and an outer membrane that suspends a transducer membrane within the interior of the support structure. The transducer membrane is selected for its acoustic and piezoelectric properties and is preferably a polymer such as P(VDF-TrFE). The outer suspension membrane is selected primarily for its mechanical properties. Portions of the suspension membrane may be removed in order to reduce mechanical drag encountered during movement of the device in a liquid. The transducer membrane includes at least one active area that is poled to provide a piezoelectrically strong region. Electrical charge generated at the active area is amplified at a preamp for transmission to remote equipment.
