摘要:
A VCSEL settling fixture provides for a plurality of VCSEL chip packages to be selectively tested within a burn-in or environmental chamber having a remote pendant controller. The settling fixture includes a mounting frame including a plurality of recesses and throughbores for positioning and aligning the VCSEL's on the mounting frame. The mounting frame further includes a plurality of terminal blocks in proximity to the recesses for interconnecting the mounting frame with the controller. An activation system including a plurality of electrical contacts electrically connects the individual VCSEL chip packages with the terminal blocks so that the controller can selectively trigger a laser output from the VCSEL chip package.

A comprehesive product dispensing system including a product/carrier dispensing system. The product carrier dispensing system comprising a carrier dispensing system and a product dispensing system. The product dispensing system including a product dispensing device and a product dispensing control system. The product dispensing control system includes a flowmeter and a controller. The controller regulates the injection rate of product injected into the carrier and the flowmeter provides feedback to the controller for regulating the injection rate of product. Product is dispensed from product containers which may be filled via a closed transfer delivery system for safe product handling and transfer.

The present invention provides methods, kits, and compositions for detecting mutations in transient receptor potential cation channel, subfamily V, member 4 (TRPV4). In particular, mutations are detected in TRPV4 to detect diseases such as scapuloperoneal spinal muscular atrophy (SPSMA) and hereditary motor and sensory neuropathy type IIC (HMSN IIC) or Charcot-Marie-Tooth disease type 2C (CMT2C).

摘要:
A method of integrating an optoelectronic device, for example a vertical cavity surface emitting laser, onto the electronic substrate of a parallel optical transceiver package by positioning and maintaining the exact relative alignment of the optoelectronic device relative to the electronic substrate for application of adhesive and curing. The method includes the utilization of a multi-piece fixture which clamps the elements into position and maintains position throughout the curing process. Alternatively, the fixture can comprise a unitary assembly for clamping the elements into position and maintaining their position throughout the curing process.
摘要:
A system including a cabinet for intaking or discharging a gas while minimizing external duct noise and a gas duct for attachment to a housing with the gas duct having a smoothly curved passageway therein with each portion of the passageway having a cross sectional area which is sufficiently large so that the ratio of the inertia forces to viscous forces within the passageway is sufficiently small so that a laminar flow condition is maintained throughout the gas duct.
摘要:
A barrel elastomer mount having a first hollow frustum composed of an elastomer and having a first end and a second end with the first end of the first hollow frustum having an interior diameter larger than an external diameter of the second end of the first hollow frustum; and a second hollow frustum composed of an elastomer having a first end and a second end with the first end of the second hollow frustum having an interior diameter larger than an external diameter of the second end of the second hollow frustum. The first hollow frustum is securely attached to the second hollow frustum at the first end of the first hollow frustum and at the first end of the second hollow frustum creating an enclosed cavity whereby the walls of the elastomer mount provide tension and shear resistance to shock and vibrational forces as well as to compressive static forces.

摘要:
The invention discloses a pulsating chlorination machine for purification of city water. The machine includes a body, two ends of which are respectively a water inlet and outlet end between which a converging pipe, a throat pipe and a diverging pipe are connected in turn; and a liquefied chlorine input port located below a middle part of the throat pipe and connecting with the throat pipe via a cone-shaped valve seat. A normally closed cone-shaped valve rod is mounted over the cone-shaped valve seat and inserted into the throat pipe through a vertical circular hole on a top of the body, and moves up and down under the control of a pulsating electromagnetic executive mechanism to open/close the liquefied chlorine input port. Through the liquefied chlorine input port the liquefied chlorine flows into the throat pipe and out from the diverging pipe and then into a clear-water reservoir.
摘要:
The present invention provides a method for designing a frequency-shifting isolator system that includes selecting, an impact absorption envelope; a geometry for the isolator mount system; and an elastomeric dampening material formed in the selected geometry. The isolator mount system is preferably configured to shift frequencies at predetermined displacements upon impact, at or before the system attains resonance.
