摘要:
A fiber optic tester (10) broadly comprises a testing unit (16) to take measurements across two test points (27), a processing unit (18) to locate faults by analyzing the measurements, a switching unit (20) that can connect termination points (13) of a electrical circuit (12) to the test points (27) in a sequence controlled by the processing unit (18), and a fiber unit (22) to test a optical circuit (14). The tester (10) may also include an electrical harness (24) or an optical harness to connect the electrical circuit (12) to the switching unit (20) or the optical circuit (14) to the fiber unit (22). The processing unit (18) is preferably programed with interconnection information of the circuits (12,14) and internal characteristics of the tester (10). Using the interconnection information and the internal characteristics, the processing unit (18) may accurately detect faults within the circuits (12,14).

摘要:
A device to transmit an audio signal to a user comprises a transducer and a support. The support is configured for placement on the eardrum to drive the eardrum. The transducer is coupled to the support at a first outer location to decrease occlusion and a second inner location to drive the eardrum. The transducer may comprise one or more of an electromagnetic balanced armature transducer, a piezoelectric transducer, a magnetostrictive transducer, a photostrictive transducer, or a coil and magnet. The device may find use with open canal hearing aids.

The present invention is a disposable sensor for use with a device that quantifies analytes in a gaseous sample. It comprises (i) a sensing element, (ii) a means for interfacing the disposable sensor with a gas analysis device, and (iii) a housing. When used with a device that can quantify the concentration of an analyte in a gas sample, the present invention facilitates the use of exhaled breath analysis as a clinical tool.
摘要:
A device to transmit an audio signal comprises at least one light source configured to transmit the audio signal with at least one wavelength of light. At least one detector is configured to detect the audio signal and generate at least one electrical signal in response to the at least one wavelength of light. A transducer is supported with and configured to vibrate at least one of an eardrum, an ossicle or a cochlea. Active circuitry is coupled to the transducer to drive the transducer in response to the at least one electrical signal, so as to provide the user with high quality sound.
摘要:
An automatic apparatus for leveling suspended articles or hung objects to an angle relative to a reference. The shift lever assembly (112), used as a gravity reference, is activated when the pendulum member swings horizontally in response to slightest inclination or tilt, thereby causing the conductor pin (114.14) to contact one side of a pair of conductor plates (114.24b) or (114.24b). The contacting of the conductor pin to one side of the pair of conductor plates (114.24b) or (114.24b) completes the electrical circuit and allows the electrical storage device (118) to provide electrical current to the planetary motor (116), causing it to rotate. The turning of the planetary motor (116) causes the shift lever assembly (112) to automatically shift the elongated lever arm (112.10) against the rigid axle (122.22), thereby shifting the center of balance of the object in the opposite direction of the rotation of the wheel-like driven gear (112.20). Leveling occurs when the elongated lever arm (112.10) returns to its original vertical orientation, the conductor pin (114.14) is no longer in contact with either side of the pair of conductor plates (114.24a) or (114.24b), and the motor stops turning.

摘要:
Techniques for performing an accounts payable process may include receiving transaction data including at least one of invoice data, purchase order data, and vendor data; and verifying a transaction by matching a dynamic data set of client-specified multi-dimensional criteria to the transaction data. An accounts payable system may include a host system in communication with one or more client systems. The host system may include a matching database configured to receive an accounts payable file including at least one of invoice data, purchase order data, and vendor data; and verify a transaction by matching a dynamic data set of client-specified multi-dimensional records to attributes of the accounts payable file.
摘要:
A hip joint prosthesis that has a strap plate and a hollow, tapered femoral neck subassembly. The femoral neck includes a flanged force plate that radiates from a head stem base and abuts the femur. Several longitudinal ridges and/or an annular recess or other surface treatment at the head stem base facilitates retention in the femur. Shaped surfaces of a femoral neck at the strap plate interlock in non-rotational engagement with a bore of the head stem base. A tapered stem projects from the force plate and supports a ball head. The strap plate includes laterally and longitudinally displaced elongated fastener holes and stress relieving recesses and/or channels. Fasteners anchor the strap plate to the femoral shaft. A shouldered bolt mounts through the femoral neck to engage the ball head base and draw the ball head base and ball head toward the strap plate and contain the prosthesis to the femur.
