Abstract: The present invention discloses a method and a device for processing optical signals in a computer mouse, which is related to electric digital data processing. The method is that the relative displacement vector between the mouse device and the illuminated object surface producing laser speckles is reflected by means of collecting movement information of laser speckle signals. The device for carrying out the method consists of a mouse body; inside said mouse body, an amplifying and shaping module, a direction identifying and counting module and a computer interface circuit for processing photoelectric signals are disposed and connected in sequence, characterized in that, said device further includes at least one laser device and a photo sensor for receiving laser speckle signals from the object surface illuminated by laser beams. Said photo sensor transfers the received photoelectric signals to the amplifying and shaping module.

Abstract: A method of adjusting received speech volume in a handset is disclosed. The method comprises initialize a variable BFI_FACTOR as 1. Using the BFI (bad frame indicator) to determine whether a current received speech frame is erroneous or not. If the current received speech frame is not erroneous, determining if the BFI_FACTOR is less than one and if so incrementing the BFI_FACTOR. If the BFI indicates an erroneous frame, determining if the BFI_FACTOR is above a minimum value and if so decrementing the BFI_FACTOR. Finally, the current speech signal is multiplied by the BFI_FACTOR and played to the user.

Abstract: An electronic device moldable to form a leadless electronic package and a method of forming the electronic device are provided. The electronic device comprises a die pad adapted for attachment of a die and a frame surrounding the die pad. A plurality of leads extend from the frame towards the die pad such that each lead has a bonding site on a top surface thereof configured for attachment of a bonding wire. The said leads include a first set of leads having bonding sites located substantially on a first plane and a second set of leads having bonding sites located substantially on a second plane that is parallel to but spaced from the first plane.

Abstract: A method and apparatus is provided for molding a semiconductor device in a mold including two mold halves. One mold half includes a compressible sealing mechanism constructed and configured to exert a sealing pressure between a surface of the mold half and a surface of a semiconductor device located in the mold. A compliant tape is positionable onto the mold half comprising the sealing mechanism between the semiconductor device and the sealing mechanism for molding of the semiconductor device.

Abstract: A fertility determining system employing hormone level measuring apparatus on selected days in a menstrual cycle to determine the levels of analytes, i.e., estrone-3-glucuronide (“E3G”) and luteinizing hormone (“LH”), in early morning urine. The fertility/infertility signalling algorithm relies upon data characterizing the user earlier in that menstrual cycle, and also upon her analyte pattern in past recent cycles. At a point in a menstrual cycle which is user-dependent, the early morning E3G urine level is compared against the lower E3G level earlier in the cycle. The beginning of the fertile period is signalled when a sufficient E3G increase occurs. The end of the fertile period (and, correspondingly, the reestablishment of a period requiring no contraception) is signalled a period after the LH surge. In the absence of an LH surge in any subject, the end of the fertile phase is signalled a period of time following the peak of the E3G urinary metabolite of estradiol.

Abstract: Compounds for use in the treatment of heart disease include a superoxide scavenger and an organic nitrate or nitrite moiety. The compounds can be represented by the formula (A)n(B)m, in which A is a superoxide scavenger, B is an organic nitrate or organic nitrite moiety, and n and m are values between 1 and 8. These compounds do not suffer from the problem of patient tolerance that is associated with the use of conventional agents such as organic nitrates.

Abstract: The present invention discloses a foldable container, which comprises a base panel and a pair of folding panels coupled with the base panel through folding means, having a first load-carrying arrangement positioned on the base panel and a second load-carrying arrangement provided at the folding panels, wherein the first load-carrying arrangement and the second load-carrying arrangement are pivotally connected or so as to ensure the folding panels foldable with respect to the base panel thereby reducing the volumetric space of the container; since the second load-carrying arrangement is adapted for withstanding substantial force, so that the foldable container could be moved by conventional hangers and could be stacked in a convenient manner.

Abstract: Disclosed is a method of detecting a retarded cycle in a human female subject experiencing same, the method comprising the steps of obtaining a sample of body fluid from the subject on each of a plurality of, but not less than three, days; testing each of the plurality of samples to determine the concentration therein of at least one analyte of significance in the ovulatory cycle; comparing a result determined from said testing with a predetermined threshold value; and, if said determined result is different from the threshold value; declaring the cycle, during which the samples were taken, to be a retarded cycle.

Abstract: The present invention provides a ferrite-based spheroidal graphite cast iron containing the following elements in the following contents in % by weight: C: 3.1 to 4.0%; Si: 3.6 to 4.6%; Mo: 0.3 to 1.0%; V: 0.1 to 1.0%; Mn: 0.15 to 1.6%; and Mg: 0.02 to 0.10%, and the total content of V and Mn is 0.3 to 2.0 wt %, and an exhaust system component using the spheroidal graphite cast iron. Thus, the ferrite-based spheroidal graphite cast iron having higher heat resistance than that of a conventional high Si spheroidal graphite cast iron that can be produced inexpensively by a simple method.

Abstract: In a system having a switching device in a first location, and an extending device in a second location, a method of providing a communications link between (i) a first phone associated with the extending device and (ii) a second phone local to the second location and not associated with the extending device includes analyzing parameters associated with the first phone and the second phone so as to determine that the first phone and the second phone are local to the second location. The method further includes separating signaling data associated with the communications link from voice traffic associated with the communications link. The method further includes directing the signaling data through the switching device via an extension link between the switching device and the extending device, and directing the voice traffic between the first phone and the second phone.

Abstract: The present invention encompasses apparatus and methods for determining variations in estimated signal-generator parameters derived from signals created by signal-generators, such as signal-generators within organs of the body, such as brain, head, spinal cord, and muscles. The present invention is particularly useful when more than one signal generator is non-zero in part or all of the time-interval analyzed. The parameters of a signal-generator that may be of interest include, but are not limited to, magnitude, location, and/or orientation, over single or multiple points in time.

Abstract: The invention provides a method of degrading nitrate esters by exposing a spension of a nitrate ester to a combined culture of Sclerotium rolfsii ATCC 24459 and Fusarium Solani IFO 31093. This allows an alleviation of environmental difficulties associated with the demilitarization of nitrocellulose base gun propellants and for the bioremediation of soils contaminated with such nitrocellulose based materials.
