  • Publication number: 20240077416
    Abstract: Gas quantity in a pixel may be estimated based on spectral matched filtering. Image data associated with a scene may be received. The scene may comprise a plurality of pixels. Next, a spectral matched filter may be constructed for a predetermined gas and based on the image data. A quantity of the predetermined gas may then be estimated in at least one of the plurality of pixels by applying the spectral matched filter to the image data.

  • Patent number: 10784745
    Abstract: A stator for an electrical machine (e.g., a motor or generator) is described. The stator includes a stator core consisting of a plurality of axially adjacent generally annular laminations. The stator has axially extending stator teeth between adjacent pairs of which are formed axially extending stator slots for receiving conductors of a stator winding. At least one of the stator teeth includes an axially extending cooling passageway through which a cooling fluid flows in use. The electrical machine can include means for circulating cooling fluid through the cooling passageway(s) to cool the stacked laminations and means for circulating air around the stator along an air cooling circuit where the circulated air is cooled by the stator laminations and there is no need for a separate heat exchanger.

  • Patent number: 7880397
    Abstract: The described DC to AC inverter efficiently controls the amount of electrical power used to drive a cold cathode fluorescent lamp (CCFL). Additionally, during striking of the CCFL, a higher energy initial energy pulse is used. During normal operation, a lower energy pulse is used.

  • Publication number: 20070003613
    Abstract: The present invention provides novel compositions in the form of a powder, capsule, liquid or lozenge, and methods for administering said novel compositions to assist the body in its ability to maintain a reasonable homeostatic mechanism for compensating for chronic internal acidity. The composition may contain several active ingredients, such as potassium bicarbonate, citric acid, calcium citrate, magnesium citrate, glycine, and licorice. The composition may also contain other inactive excipients, such as hypoallergenic rice, flour, glycerine, tangerine oil and gelatin. Following oral administration, the composition is rapidly broken down and absorbed into the systemic circulation. Upon absorption, the individual components are able to assist the physiological acid-alkaline buffer systems, promote anti-anxiety effects, and decrease inflammation in the digestive system.

  • Patent number: 6900600
    Abstract: The described DC to AC inverter efficiently controls the amount of electrical power used to drive a cold cathode fluorescent lamp (CCFL). The inverter uses a full bridge that is controlled to deliver energy to the CCFL using pulse width modulation (PWM). Additionally, during striking of the CCFL, a wider initial energy pulse is used. During normal operation, a lower energy pulse is used.
