Therein, the calibration data is based on at least one testing process performed on the control unit (10) and is required for a faultless operation of the control unit (10). Further, according to a method for generating an activation key for a control unit (10) of a battery system (100) an activation key is generated based on such security identifier and output from the control unit (10). The invention further relates to an activation method for such control unit (10), wherein a control unit (10) is activated in response to the validation of such security identifier.

摘要： Optical detectors and methods of forming them are provided. The detector includes: a controller, pump and probe laser generators that generate modulated pump laser and probe lasers, respectively, a microring cavity that receives the lasers, a microbridge, and a photodetector. The microring cavity includes covered and exposed portions. The microbridge is suspended above the exposed portion and interacts with an evanescent optical field. The wavelength and modulated power of the pump laser are controlled to generate the evanescent optical field that excites the microbridge to resonance. The microbridge absorbs optical radiation which changes the resonance frequency proportionately. The probe laser is modulated in proportion to a vibration amplitude of the microbridge to form a modulated probe laser which is provided to the photodetector. The controller receives data from the photodetector, determines a change in resonance frequency, and calculates the amount of absorbed radiation from the change in resonance frequency.

摘要： A photodiode comprising a photoactive spinel oxide layer is described. This photoactive spinel oxide layer forms a contact with both a light absorption layer of quantum dots, quantum wires, or quantum rods, and an inorganic substrate layer. In some embodiments, the inorganic substrate layer and the photoactive spinel oxide layer form an isotype junction. Methods of characterizing the photodiode are provided and demonstrate commercially relevant electrical and optoelectronic properties, particularly the ability to operate as a photodetector with a high photosensitivity. An economical process for preparing the photodiode is provided as well as applications.

摘要： A lens allows infrared light to pass therethrough. An infrared sensor includes infrared detection elements arranged in two or more columns. The infrared sensor is rotated around a scan rotation axis that passes through part of the lens to scan a detection range, and outputs an output signal indicating a thermal image of the detection range. At least two infrared detection elements in the infrared sensor are located at positions displaced from each other with respect to the scan rotation axis. Among the infrared detection elements, the number of first infrared detection elements having a smaller half-width of a point spread function in a scan direction than that in the direction of the scan rotation axis is larger than the number of second infrared detection elements having a larger half-width of a point spread function in the scan direction than that in the direction of the scan rotation axis.

摘要： A method of estimating heat distribution of an image display unit includes: calculating, based on image data, an average current value of a pixel area in a display surface, the pixel area including at least one pixel in an image display unit, the image display unit including pixels arranged therein; calculating heat generation amount data by multiplying the calculated average current value by a predetermined current-heat conversion coefficient to convert the calculated average current value into a value corresponding to an amount of heat generation; and adding the heat generation amount data to a value of a first heat distribution table to update the first heat distribution table, and creating a new first heat distribution table by performing a two-dimensional low pass filter process on the updated table before multiplying a value of the processed table by a predetermined heat dissipation coefficient, at every predetermined period.

摘要： A direction-selective interferometric optical filter for spectrometric devices, at least includes an arrangement of two layered one-dimensional photonic structures. Each of the two structures contains a defect layer, and each photonic structure has a dispersion function in the energy momentum space (E, kx, ky), wherein kx and ky are momentum components of transmitted photons of the photonic structures for a defined energy (frequency/wavelength) E in the energy momentum space. Both photonic structures have opposite interfaces which are at a plane-parallel distance from one another. In this case, the dispersion functions of both photonic structures cross or intersect in the energy momentum space and produce a cut set of rays of waves on the surfaces of the dispersion functions at a particular energy, wherein a ray of waves contains waves selectively chosen through the filter at an angle, while other waves are reflected by the filter at other angles.

摘要： A soda-lime-silica glass container and related methods of manufacturing. A black-strikable glass composition having a base glass portion and a latent colorant portion is prepared. The base glass portion includes soda-lime-silica glass materials and one or more blue colorant materials, and the latent colorant portion includes cuprous oxide (Cu2O), stannous oxide (SnO), bismuth oxide (Bi2O3), and carbon (C). Glass containers may be formed from the black-strikable glass composition, and these glass containers may be heated to a temperature greater than 600 degrees Celsius to strike black therein. The glass containers formed from the black-strikable glass composition may be inspected—before or after striking—by infrared inspection equipment.
