Abstract: An apparatus aspect of the disclosure includes a lidar transmitter emitting laser beams, and scan mirrors (or assemblies) angularly adjustable to deflect the beams in orthogonal directions. In one aspect, afocal optics magnify deflection, a transmitter aperture transmits the beam, and a lidar receiver doesn't share the transmitter aperture. In another aspect, auxiliary optics calibrate the deflection. A method aspect of the disclosure includes noticing and responding to a remote source, using a local laser, adjustable scan mirror or assembly, afocal deflection magnifier, transmission aperture and separate receiver. Method steps described include operating the receiver to notice and determine the location of the remote source, and controlling the transmitter to direct laser light back toward that location.

Abstract: Separate reception/transmission apertures enhance pointing: reception is more efficient than transmission (kept smaller for MEMS steering). Apparatus aspects of the invention include lidar transmitters emitting laser beams, and scan mirrors (or assemblies) angularly adjustable to deflect the beams in orthogonal directions. In one aspect, afocal optics magnify deflection; a transmitter aperture transmits the beam; a lidar receiver doesn't share the transmitter aperture. In another aspect, auxiliary optics calibrate the deflection. A method aspect of the invention notices and responds to a remote source—using a similar local laser, adjustable scan mirror or assembly, afocal deflection magnifier, transmission aperture and separate receiver. Method steps include operating the receiver to notice and determine location of the remote source; and controlling the transmitter to direct laser light back toward that location.

Abstract: A delivery device for thin-film material deposition has at least first, second, and third inlet ports for receiving a common supply for a first, a second and a third gaseous material, respectively. Each of the first, second, and third elongated emissive channels allow gaseous fluid communication with one of corresponding first, second, and third inlet ports. The delivery device can be formed from apertured plates, superposed to define a network of interconnecting supply chambers and directing channels for routing each of the gaseous materials from its corresponding inlet port to a corresponding plurality of elongated emissive channels. The delivery device comprises a diffusing channel formed by a relief pattern between facing plates. Also disclosed is a process for thin film deposition. Finally, more generally, a flow diffuser and a corresponding method of diffusing flow is disclosed.

Abstract: A method for forming an electronic device provides a metallic carrier having a retaining surface and secures a contact surface of a metallic substrate material against the retaining surface of the metallic carrier. The substrate is processed to form the electronic device thereon; and the metallic substrate material released from the metallic carrier, to yield the completed electronic device.

Abstract: A method for forming an electronic device on a flexible substrate conditions the surface of a carrier to form a holding area for retaining the flexible substrate. A contact surface of the flexible substrate is applied against the carrier with an intermediate binding material applied between at least the holding area of the carrier and the corresponding area of the contact surface. Entrapped gas between the flexible substrate and the carrier is removed and the substrate processed to form the electronic device thereon. The substrate can then be removed from the holding area to yield the resultant electronic device.

Abstract: A multimode source, such as a high-power laser diode bar, to pump an Nd3+ doped region defined in a cavity of a monolithic crystal structure. The axial length L1 of the doped region is chosen to optimize energy absorption from the multimode source while minimizing resonant re-absorption loss to unpumped Nd3+ ions. The next proximal cavity length L2 is an undoped region whose length is chosen to optimize the lowest order or fundamental spatial mode (“mode 9”) of the cavity. Advantageously, multi-parameter numerical optimization techniques may be employed in which the parameter set (e.g., doped length, L1, doping concentration, pump beam spot size, micro laser cavity length, and output coupler reflectivity) is varied to determine the overall optimal length L1opt.

Abstract: The mode and wavelength of a conventional, multi-mode, wide-stripe laser diode is converted in an Nd3+ ion-doped laser host crystal to a stable, single-mode output that falls within the spectral region required for pumping EDFA amplifying structures. The host crystal absorbs radiation from the diode that corresponds with the 4I9/2→4F5/2 absorption band of its Nd3+ ions, and re-radiates into the 4F3/2→4I9/2, 4F3/2→4I11/2, and 4F3/2→4I13/2 transitions which release photon energy that can be utilized by amplifying structures doped with Er3+ and/or Yb3+. The spatial mode of the multimode laser diode is converted to single-mode by enclosing the Nd3+-doped host laser crystal within a laser cavity that has a fundamental mode size large enough to encircle the spatial extent of the beam emanating from the laser diode.

Abstract: A high speed optical receiver comprises a photonic detector having an active aperture area dimensioned to minimize capacitance effects commensurate with achieving the desired signaling speed, and a compound parabolic reflector having a surface contour described by rotating a parabolic arc about a rotational axis, the axis of said parabolic arc making an angle with the rotational axis proportional to the conical angle of the incident light to be gathered, the reflector having a plurality of focii defining the perimeter of an exit pupil not exceeding the area of said photonic detector aperture. The compound reflector contour may advantageously be formed at the end of a length of optical fiber that is positioned at the detector aperture, incident light being admitted to the other end of the fiber through a focusing element which may be a lens, mirror, or holographic phase mask.

Abstract: An underground storage tank installation. The excavation is to a predetermined depth to permit placement of a storage tank of desired size therein below ground level. At least a pair of opposing side walls of the excavation are sloped to minimize the danger of collapse. The excavation is provided with a base layer of footing material by appropriate backfill and a double shell storage tank is rested on the base layer in the excavation. Double shell piping conduits and a leak detector is installed between the shell and ground level. Backfill material is placed into the excavation to cover the tank and piping and leak detector structure to a height adjacent ground level. A solid slab is positioned over the tank and the backfill layers with appropriate apertures to permit access to the underground piping conduits and the leak detector. The excavation, backfilling, placement of the tank, piping and detector and pouring of the slab are accomplished without the necessity of personnel entering the excavation.

Abstract: A system to detect leaks, monitor levels, activate alarms, etc. in which a specific material in the system dissolves or disintegrates on contact with a liquid, gas or vapor which is to be monitored.
