  • Publication number: 20220069546
    Abstract: A VCSEL device having non-coaxial-with-one-another apertures and/or rotationally asymmetric apertures formed in layer(s) of the VCSEL structure to define more than one spatial mode in a light output in operation of the device. An array of such VCSEL devices configured to have different spatial modes at the output of different constituent VCSEL devices. Spatial asymmetry of structure of the constituent VCSEL devices and, therefore, arrays of VCSEL devices causes the overall light output to form an irregular grid of output spots of light. When the VCSEL array is equipped with an appropriate lens array, the spatial components of the light output of the VCSEL array are caused to overlap in the far at the imaging plane in a multiple spatial (and spectral) mode fashion, thereby reducing speckle in imaging applications.

  • Publication number: 20210409618
    Abstract: An electronic device having a display with an infrared component (such as a camera, a light source) behind the display. The layer of the display is transparent to infrared light at which the infrared component operates. Infrared sensing functions, when implemented by the component, may be accomplished by transmission of infrared light through the layer of the display, thereby removing the conventional need for cut-outs or holes in the display plane and maximizing the display area.

  • Publication number: 20210399153
    Abstract: Semiconductor structures including optically-transparent metamorphic buffer regions, devices employing such structures, and methods of fabrication. The optically-transparent metamorphic buffer is grown to provide a lattice constant transition between a smaller lattice constant and a larger lattice constant (or vice-versa), allowing materials with two different lattice constants to be monolithically integrated. Such buffer layer may include at least two elements from group V of the periodic table. The optically-transparent metamorphic buffer region may include digital-alloy superlattice structure (s) to confine material defects to the metamorphic buffer layer, and improve electrical properties of the metamorphic buffer layer, thereby improving the electronic properties of electronic devices such as optoelectronic devices and photovoltaic cells. Photonic devices such as solar cells and optical detectors containing such semiconductor structures.

  • Publication number: 20210234063
    Abstract: A stacked superluminescent light-emitting diode having multiple active regions coupled together using and via tunnel junctions. The material compositions of each of the active regions (corresponding quantum wells and/or barriers) differ from one another to provide a controlled different light emission at wavelength (and/or wavelength range) for each junction. In operation of the device, the spectral width of the aggregate light output generated by different junctions is defined by all the junctions, thereby producing a spectrally-broader emission than that of any single, separately taken junction within the device. Thus, the device is configured to operate as a broadband infrared light source.

  • Publication number: 20190280143
    Abstract: Semiconductor light absorption devices such as multi junction photovoltaic cells include a chirped distributed Bragg reflector beneath a junction. The chirped distributed Bragg reflector provides a high reflectivity over a broad range of wavelengths and has improved angular tolerance so as to provide increased absorption within an overlying junction over a broader range of wavelengths and incident angles.

  • Patent number: 9498581
    Abstract: The present disclosure describes a needle guard device or system that can be used with drugs requiring reconstitution. The needle guard is preferably a passive needle guard that can be used during reconstitution without activating the safety mechanism. Following administration of the medication, the needle guard shields a user from inadvertent needle sticks by extending a protective shield over the needle.

  • Patent number: 9248242
    Abstract: A safety device for a medicine cartridge comprising a body for receiving a cartridge, a guard for covering a used needle, a plunger to dispense medicine from the cartridge and a spring for activation of the guard. The trigger fingers of the guard are spaced to avoid or minimize contact with the spring flange during assembly to avoid trigger finger unseating. An elongated trigger finger head enables the device to activate for all known syringe and syringe plunger tolerances. The spring end coils have larger diameter than the inner coils to reduce the likelihood of the spring end coil end interfering with the cartridge subassembly. Syringe capture features are configured to retain a syringe having a small round or conventional cut flange in place during use and reduce the stress on the syringe flange during insertion while maintaining the ability to hold the syringe in place during use.

  • Patent number: 8372044
    Abstract: The present invention provides an injection device including a syringe having a distal end for receiving a needle, and a plunger inserted into a proximal end. A guard is slidable on the syringe, has a proximal end, a distal end, and is biased from a first position wherein the needle is exposed toward a second position wherein the guard covers the needle. The syringe includes a body having a central cylindrical opening for receiving a medicine and the plunger, and further includes a pair of longitudinally extending members on opposite sides of the body. The injection device includes cooperating detents for retaining the guard and syringe in the first and second positions. A latch member is engageable by the plunger as the plunger is depressed to release the cooperating detents. Upon release, a spring element biases the guard toward the second position.

  • Patent number: 8298193
    Abstract: A passive needle safety device for protecting the needle of an injection syringe after medication has been delivered to a patient comprising a body that can hold a syringe, a telescoping guard fitting over the body, and a spring deployed between the guard and body such that the guard is urged in an extend configuration distally relative to the body, the improvement comprising, trigger fingers for holding the guard and body together in an un-extended configuration against the force of the spring, and a plunger rod with a plunger head which pushes against the trigger fingers, the head having an angled surface that provides a lateral component of force to the trigger fingers to displace them from the latched configuration to an unlatched configuration.

  • Patent number: 7981088
    Abstract: A syringe system for the administration of lyophilized drugs includes a syringe barrel and a stopper and a needled guard each coupled with the syringe barrel. A reconstitution plunger is removably coupled with the stopper. A diluent is withdrawn from the syringe into a vial containing a lyophilized drug, and the diluent and drug are mixed to form a therapeutic agent. The reconstitution plunger is then replaced by an administration plunger. The length of the reconstitution plunger is greater than the length of the administration plunger in order to prevent activation of the needle guard during reconstitution. Alternatively, a single plunger system may be used in which the plunger can transition from an extended length during reconstitution to a shortened length during administration. During administration, a radial element of the plunger contacts latch members of the needle guard, whereupon the shield advances to an extended position covering the needle.

  • Publication number: 20110054411
    Abstract: A device that is used in conjunction with a needle-based medication injection device (e.g. a prefilled syringe) that prevents needle stick injuries after the medication has been injected into a patient. The used needle is shielded by a cylindrical needle guard that surrounds and extends beyond the needle tip. In a preferred embodiment, before the needle is inserted into the patient, the needle guard projects forward to substantially hide visibility of the needle for safety and to reduce patient anxiety.
