Title: Method for producing packaging items
Inventor: ROLLE JEAN-CLAUDE
IPC: B29C67/20
Filed: 1996-07-04
Abstract: The inventive packaging item is e.g. a tray for packing fresh meat. It has at least on its bottom part (10) grooves (11) which open towards the inside of the packaging item. The openings of these grooves are narrower than the inside part of the grooves. If the groove opening is sufficiently narrow e.g. 1 mm or less, unwanted liquid oozing out of the packed meat is trapped in these grooves (11) and such separated from the meat and kept out of sight of a potential buyer.

Title: Singular fiber to bundle illumination with optical coupler
Inventor: GOULIATOS ZAFIRIOS
IPC: G02B6/26
Filed: 1996-07-31
Abstract: A gradient index (GRIN) lens (16) couples light from a single fiber (12) optic into a fiber bundle (14) or directly into the input port (104) of an illumination device, such as a medical illumination device. The single fiber (12) optic provides a high intensity beam of light having a high NA. An entry face (18) of the GRIN lens (16) is positioned adjacent to an exit aperture of the fiber (12) within the near field (28) of the fiber and thereby receives a beam having a substantially uniform cross section, rather than a Gaussian cross section as would occur with the GRIN lens (16) positioned in the far field of the fiber (12). An exit face of the GRIN lens (100) is positioned adjacent to the fiber bundle or input port (104) of the illumination device (106). As such, the GRIN lens effectively images the exit aperture of the fiber (102) of the input aperture of the fiber bundle as input port (104). The optical characteristics of the GRIN lens (100), including its length and radial variation in index of refraction, are selected to reduce the NA of light output from the fiber (102) to a value appropriate for use with the illumination device (106). An optical coupler employing the GRIN lens (100) is described as well as an entire optical system including a source of light (108), an off-axis coupler (110) for coupling light into the fiber (102), a gradient index lens (100), and an endoscope (106). A mechanical housing (105) for holding the single fiber (101) and GRIN lens (160) and for facilitating connection to a fiber bundle or input port (106) is also described.

Title: Method and system responsive to myoelectrical activity for triggering ventilatory support
Inventor: SINDERBY CHRISTER
IPC: A61M16/00
Filed: 1998-02-27
Abstract: A method and device for triggering ventilatory support to assist the patient's respiration. Myoelectrical activity of a patient's respiratory-related muscle is sensed to detect respiratory effort, and to produce a myoelectrical signal representative of the sensed muscle myoelectrical activity. Respiratory flow and pressure can also be measured to produce respective respiratory pressure and respiratory flow signals. A logic trigger circuit triggers ventilatory support in relation to the myoelectrical signal, respiratory flow signal and/or respiratory pressure signal to assist respiration of the patient. The amplitude of the myolectrical signal is compared to a given threshold, and ventilatory support is triggered when the amplitude of the myoelectrical signal is higher than this threshold. Increment of myoelectrical signal amplitude can also be detected to trigger ventilatory support, while decrement of the myoelectrical signal amplitude can be detected to request non-triggering of the ventilatory support.

Title: Thin film formation process
Inventor: IWANE MASAAKI
IPC: H01L21/20
Filed: 1998-03-23
Abstract: A process for thin film formation is provided which comprises a step of separation of a substrate constituted of a nonporous Si layer, a porous Si layer formed thereon, and a less porous Si layer formed further thereon into the nonporous Si layer and the less porous Si layer at the porous Si layer, wherein the separation is caused by projecting a laser beam through the side face of the substrate.  From the separated substrate, an SOI substrate is prepared, and the non porous Si layer is recycled to the SOI substrate production process.  This SOI substrate production process saves the consumption of the material and lowers the production cost.  The substrates are separated definitely.  A process for producing a photoelectric transducing apparatus such as solar cells with material saving and low cost is also provided in which the porous layer is separated definitely without strong adhesion between the substrate and a jig.

Abstract: This disclosure covers a method of equalization for a high speed, indoor wireless local area network . The invention is designed so that the terminal equipment is as simple as possible while the hardware required for adaptive filtering, antenna diversity and frequency diversity is implemented almost entirely at the base station. The system uses pre-equalization for the downlink and post-equalization for the uplink.  Antenna diversity and adaptive rate frequency diversity are used together to reduce the effects of frequency selective multipath fading to ensure that the equalizer can correct the distortion introduced by the radio channel.

Abstract: An impedance regulator system and method which offers a large effective high-frequency block to isolate RF signals transmitted  on  power  lines  is  presented.    High-current inductors in series are inductively coupled over the  RF band to physically smaller,  low-current coupling inductors.   The coupling inductors induce a degenerative or canceling at RF frequencies in the high-current inductors,  resulting in the effective inductor increase and hence higher impedance over the RF band.

Abstract: Digital audio recording equipment (12) is used to record modulated signals, such as the RF test signals generated by test modems. If the modulated signals are outside the audio frequency range, they are down-converted into the audio frequency range using a mixer (4), local oscillator (6) and a filter (8). The digitally converted data are recorded onto a suitable medium, such as a DAT, CD or a computer memory. The data is then disseminated for reproduction by a suitable digital audio player (12'). The reproduced audio signal may be upconverted to the desired radio frequency using a mixer (16), local oscillator (18) and a filter (20). The reproduced signal may be used to test demodulators, codecs or transceivers. The signals output by the transceiver and the reproduced signal may be recorded on different channels of the digital audio recording equipment (12). The recording equipment (12) may be used to capture RF signals for later analysis. The player (12') may be used for reproducing modulated signals for broadcast.
