Title: Method and apparatus for introducing reference impairments into video signals
Inventor: QUACCHIA MARCO
IPC: H04N17/00
Filed: 1998-12-15
Abstract: A  method  and  an  apparatus  are  provided  for introducing reference impairments into pictures to be used in subjective tests on digital video signals, in compliance with ITU-T Recommendation P.930.   The method generates blockiness distortion and/or edge busyness distortion.  For the first distortion,  areas close to picture edges are selected and, through a movement characteristics analysis, blocks are identified that belong to said areas and that are concerned only by the actual movement of the subject and,  for blocks chosen among the identified ones,  the luminance value  is  replaced by a value  linked to the individual  pixel  luminance  and  to  the  average  block luminance value.   For the second distortion,  echoes are applied that are randomly chosen in a prearranged set and that alternate at random.

Abstract: The golf course (20) of the present invention includes a larger generally open teeing area (19) and a more dispersed hole area (1-18) of the course, which comprises a series of shorter length golf holes. At the teeing area (19), the golfer will repeatedly tee and drive golf balls while aiming at one of several different targets on the range, each of which corresponds to a different hole of the hole area. The golfer records the results of these tee shots. After completing all required tee shots, the golfer proceeds to the hole area and, based on the results of the corresponding tee shot, the golfer will position a golf ball on the fairway or other portion of each of these holes and continue play in a normal fashion. In this manner, the course can provide a golf experience more resembling that of regulation golf than a par 3 or executive course without requiring as much land area.

Abstract: The present invention relates to a multiple position stand for holding container lids. In one embodiment, there is provided a rigid, frusto-conical shell segment having a large rim end and a small rim end and defining a gap that spans the length of the shell. The gap enables a hand to access the interior of the shell, so that the hand holding a container lid can maintain continuous contact with the lid until the lid is placed to rest on the rim end serving as a stand cradle. The stand is selectably positionable in a small lid support position so that the small rim end serves as the stand cradle, and the large rim end rests on a counter top or other surface to serve as the stand base. The stand is selectably positionable in a large lid support position so that the large rim end serves as the stand cradle and the small rim end serves as the stand base. There is provided a second embodiment comprising a plurality of bars that interconnect to resemble the notional frusto-conical shell segment of the first embodiment. The taper of the frusto-conical shape in both embodiments enables multiple stands to be stacked on top of each other to minimize space consumption.

Title: Improvements in brush making
Inventor: O'NEILL KILIAN JOHN
IPC: A46B9/04
Filed: 1997-12-12
Abstract: The invention relates to a process for forming a two-component, resiliently flexible joint in a personal grooming implement, whereby elastomer is injected into a void space (13) in a plastic handle (5) or head (2) at a temperature of at least 245 ~C, thereby fusing the elastomer to the plastic and forming the resiliently flexible joint. The invention further relates to a personal grooming implement including a resiliently flexible joint between a plastic material having a Vicat softening point of less than 245 ~C, and an elastomer, wherein the elastomer is fused to the plastic material such that the elastomer can be stretched to at least 120 % of its unstressed length without separation of the elastomer from the plastic. The invention provides improved adhesion between the elastomer and the plastic so that flexible joints are better able to withstand repeated flexing. The durability of the implement is thereby improved.

Title: Multi-function stalk switch
Inventor: LIDIKAY CURTIS L
IPC: B60Q1/14
Filed: 1999-07-19
Abstract: A multi-function stalk switch that incorporates a pushbutton switch, a first rotary switch and a second rotary switch onto the end of a stalk, wherein further switching functions may be executed by moving the entire stalk in either of two orthogonal planes. The stalk switch incorporates many design features that enable it to be assembled at low cost from a small number of parts. One such feature is the use of plastic-on-plastic detents to control positioning of the rotary switches so that they wipe across predetermined portions of a flexible printed circuit board. Another feature is the inclusion of a spring-loaded plunger detent riding in a concave centering mechanism that is operable to automatically return the stalk switch to its central (neutral) position after removal of external biasing forces. A further feature is the inclusion of magnets on the stalk switch and Hall effect sensors fixedly mounted nearby in order to sense movement of the magnets (and therefore the stalk) in two orthogonal planes. Further features of the invention are also disclosed.

Title: Aqueous immunologic adjuvant compositions of monophosphoryl lipid a
Inventor: CRANE R THOMAS
IPC: C07H13/06
Filed: 1998-04-01
Abstract: An aqueous adjuvant composition comprising an attenuated lipid A derivative and a surfactant or surfactants enhances the immunological response in a warm blooded animal to a protein antigen. Attenuated lipid A derivatives useful according to the subject invention include monophosphoryl lipid A and 3-O-deacylated monophosphoryl lipid A. A surfactant or mixtures of surfactants are dissolved in a solvant. 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine is a preferred surfactant. The dissolved surfactant is added to an attenuated lipid A derivative to obtain a mixture. The molar ratio of attenuated lipid A derivative to surfactant in the mixture is about 4:1. The solvent is evaporated and water is added to the resulting film. The suspension is sonicated in a 60 ~C water bath until it becomes clear. Animals administered the adjuvant formulation exhibited increased antibody responses to a given antigen as well as displayed enhanced lymphocyte proliferative and cytotoxic Tlymphocyte responses. Intranasal administration of the aqueous adjuvant composition and an antigen stimulates the production of serum and mucosal secreted IgA.

Title: Use of melatonin for preparing medicaments for treating circadian rhythm phase disorders
Inventor: LEWY ALFRED J
IPC: A61K31/4045
Filed: 1998-04-29
Abstract: A method for treating circadian rhythm disorders is described. The method involves the administration of melatonin, melatonin agonists or compounds that stimulate endogenous melatonin production so that the durations of the effective plasma concentrations of melatonin, melatonin agonists or compounds that stimulate endogenous melatonin production overlap with onset or offset of pre-treatment endogenous melatonin production, to provide a circadian-rhythm phase advance or phase delay, respectively. The methods of the invention also provide for concentration and/or duration of the effective plasma concentrations of melatonin, melatonin agonists or compounds that stimulate endogenous melatonin production to be greater in the time interval between about 8 hours before the dim light endogenous melatonin onset (DLMO) to about 4 hours after DLMO than in the time interval from about 4 hours after DLMO to about 8 hours before DLMO to achieve a circadian-rhythm phase advance. The methods of the invention also provide for concentration and/or duration of the effective plasma concentrations of melatonin, melatonin agonists or compounds that stimulate endogenous melatonin production to be greater in the time interval between about 4 hours after DLMO to about 8 hours before DLMO than in the time interval from about 8 hours before DLMO time to about 4 hours after DLMO to achieve a circadian-rhythm phase delay. In addition, the invention provides methods for regulating a human's exposure to light and dark to prevent or enhance, respectively, the human's endogenous production of melatonin. The use of melatonin antagonists, inverse agonists and melatonin inhibitory compounds such as beta-blockers for achieving a circadian-rhythm phase-shifting effect (opposite to that of melatonin administration) are also provided by the invention. The methods of the invention are illustrated by teachings for use of these methods for alleviating a variety of circadian rhythm-related disorders, including jet lag, winter depression, shift workrelated desynchronies and sleep phase disorders.
