  • Patent number: 7214925
    Abstract: A method of detecting a non-fixed object in a system (12) includes applying a light emitting or generating substance to multiple objects. The objects are illuminated with an object illuminator (13). At least one of the objects (10) is determined to be a nonmember within a known pattern of objects and is identified to be a non-fixed object in response to illumination of the objects.

  • Patent number: 7009198
    Abstract: A method of detecting a non-fixed object created during hole drilling operations on a system (12) includes applying a light emitting lubricant (25) to a drill bit (37) of a hole-drilling device (31). The light emitting lubricant adheres to foreign object debris 10 that is created during the hole drilling operations. The foreign object debris 10 can include shavings (29), portions of the drill bit (37), or the entire drill bit (37). The objects are illuminated with an object illuminator (16). At least one of the objects (10) is determined to be a nonmember within a known pattern of objects and is identified to be a non-fixed object in response to illumination of the objects.

  • Patent number: 5335194
    Abstract: A sample rate converter comprises a first finite impulse response digital filter which effects a sampling rate doubling operation, which has a relatively large number of taps and whose output is connected to a second FIR digital filter having a relatively low number of variable coefficient taps. The frequency response of the first FIR digital filter is arranged to compensate for the frequency response of the second FIR digital filter.

  • Patent number: 5221966
    Abstract: A system for converting an input television signal that contains field sequences corresponding to frames in cine film is provided. The input signal is converted into an intermediate television signal wherein there is a direct correlation between the field groups thereof and the original film frames. The intermediate signal is modified to produce and output television signal whose field rate is that of a desired television signal. For example, the input signal can be an NTSC signal produced in part from a 3:2 pull down technique, the intermediate signal may be characterized by 625 lines and 48 fields per second or characterized by 525 lines and 625 fields per second, and the output signal can be a PAL signal characterized by 625 lines and 50 fields per second. In each case, a 3:2 sequence of input signal fields (correlated with cine frames) results in pairs of fields in the output signal correlated with the cine frames.

  • Patent number: 5013833
    Abstract: There is described a product which is a highly pure substantially amorphous form of cefuroxime axetil (cefuroxime 1-acetoxyethyl ester) which is stable, which has increased absorption via the gastro-intestinal tract and has a correspondingly high level of bioavailability on oral or rectal administration.Methods of preparing the product are also described which involve the recovery of the product from a solution thereof. A preferred method is the use of spray drying techniques, though roller drying, solvent precipitation or freeze-drying are also described.Also disclosed are pharmaceutical compositions containing the product and methods for its use in medicine.

  • Patent number: 4766484
    Abstract: Apparatus for and a method of decoding a video color signal provides a digital wide band luminance signal. An analog signal V1 representing the low band luminance component of a coded video color input signal Icv, is obtained at a first analog filter 1. An analog signal Yhc representing high band luminance and chrominance components is obtained at second means (5) which subtracts the first analog signal Y1 from a delayed input signal Icv. Signal Yhc is synchronously demodulated to provide (B-Y) and (R-Y) chrominance component signals U.sub.1, V.sub.1, which are digitized. Via digital delay means, single line delayed signals Yd1, U.sub.0, V.sub.0 and double line delayed signals U.sub.-1, V.sub.-1 are obtained. High band luminance signals Yu, Yv are then obtained as a function of at least two of the respective chrominance component signals U.sub.1, U.sub.0 and U.sub.-1 ; and V.sub.-1, V.sub.0 and V.sub.-1.
