  • Patent number: 10361787
    Abstract: Methods and systems for optical alignment to a silicon photonically-enabled integrated circuit may include aligning an optical assembly to a photonics die comprising a transceiver by, at least, communicating optical signals from the optical assembly into a plurality of grating couplers in the photonics die, communicating the one or more optical signals from the plurality of grating couplers to optical taps, with each tap having a first output coupled to the transceiver and a second output coupled to a corresponding output grating coupler, and monitoring an output optical signal communicated out of said photonic chip via said output grating couplers. The monitored output optical signal may be maximized by adjusting a position of the optical assembly. The optical assembly may include an optical source assembly comprising one or more lasers or the optical assembly may comprise a fiber array. Such a fiber array may include single mode optical fibers.

  • Publication number: 20160245760
    Abstract: The invention relates to a device for measuring sheets comprising a light source and a light sensor, which are arranged such that a light beam emerging from the light source passes through the sheet and impinges on the light sensor. According to the invention, the light sensor has a dynamic range of more than 8 bits with linear resolution, or has a non-linear resolution. The invention also relates to a corresponding method. The invention makes it possible to reliably measure both a primary beam and a secondary beam of the light beam that passed through the sheet.

  • Publication number: 20060208090
    Abstract: This process allows one to create bar code and dot code labels that are sensitive to infrared, visible, and ultraviolet light with out the use of ink. This is accomplished by cutting out or otherwise removing select areas of media to create shapes identical to the outlines of data elements that would be created by infrared, ultraviolet, and visible ink printing systems. This includes but is not limited to the shape of bars in bar coding, the dots in dot coding, lettering, numbering, and images. The method of cutting out the shapes could be manual or with special automated tools, equipment, and machinery. This process offers distinct advantages that qualify it as an improvement over ink printing. It can be done more cheaply, has a stability that is more dependant on the media than the ink, can not wash off, and there are no problems involving insufficient ink and poor print quality.

  • Patent number: 7103519
    Abstract: A method and system for increasing standardization and reuse of feature driven design of automotive vehicles. An automotive vehicle is represented by a vehicle model, which includes a set of features defining vehicle functionality and information on how to implement each feature. A features database stores information on how a feature is implemented, including the physical parts it requires and the configuration of the parts. A parts database is also provided for maintaining information on vehicle parts. Coupled to the features database and the parts data base is a feature manager arranged to determine physical implementation information for each feature based on the implementation information. The physical implementation information is included in the vehicle model. A conflict manager is provided for resolving conflicts between implementations of separate features, and an optimizer for standardizing parts and implementations across multiple vehicle models.

  • Patent number: 5699857
    Abstract: An automotive heater, ventilation and air conditioning (HVAC) control system reduces overall system cost and improves system reliability by reducing the number of wire interconnects between the climate control head and the multifunction body control module. Wire reduction from as many as seven to as few as one is possible with the inventive resistively multiplex system. The inventive system combines rear defrost, airconditioning on/off and a set of mode door drive motor select signals within a single climate control head. The inventive climate control head includes a series of resistors and switches that effectively allow a vehicle user to select the various modes of HVAG system operation. The climate control head effectively combines the various possible mode signals into one analog signal that varies according to the selected mode. The single analog signal is fed into a single analog-to-digital port in the multifunction control module.

  • Patent number: 5381074
    Abstract: A lighting control system with self calibration for employing the entire physical travelling range of a dimmer switch. A lookup table and linear interpolation are used in conjunction with the voltage output of the dimmer switch in order to identify the appropriate duty cycle of a Pulse Width Modulated signal which drives the lamps in the system. Two of the values in the lookup table are default minimum and maximum values of voltage which can be expected from a worst case switch device. The system dynamically determines and stores any new maximum or minimum voltage which is received from the dimmer switch. These dynamically determined minimum and maximum values are used to replace the default values in the lookup table thus calibrating the lookup table. The calibrated lookup will take into account the operating parameters of the actual switch in the vehicle and will therefore always produce a corresponding change in illumination intensity over the entire physical range of the dimmer switch.

  • Patent number: 5311746
    Abstract: A temperature sensing device for a vehicle samples air from an interior passenger compartment to determine passenger compartment temperature by purging air in a region surrounding a temperature sensor, in favor of passenger compartment air. A sensor triggered by door operation allows the purging process to begin before a passenger enters the vehicle and the vehicle's automatic temperature control system is activated. A method of accurately measuring the temperature of air in the passenger compartment of the vehicle involves the steps of sensing that the passenger is about to enter the vehicle purging the air in the region surrounding the sensor and drawing in air from the passenger compartment, and measuring the air at the sensor after the purging step.
