Abstract: The inventive method uses data received concerning the status of various tables in the establishment, the criteria provided by the customer as well as the status of the meals being prepared in a variety of courses for customers already seated to best determine how much time a new customer will have to wait before a suitable table is available where the customer may be seated. When a customer enters the restaurant, they provide information to the hostess or host including the party size and various table preferences. The host or hostess enters this information into a computer using a keyboard touch screen input or a wireless remote device. Based upon the preferences chosen by the party, the system assigns the most predictable table and periodically scans each existing table to determine that table's status. The method gains additional accuracy by obtaining detailed kitchen status information concerning meals being prepared for each table.

Abstract: An optical system for determining the angular position of a radiating point source is disclosed, wherein radiation from a point source travels through a mask and onto the surface of a sensor. A preferred embodiment employs a plurality of mask transmission frequencies and a detector designed to be sensitive to the phases of the frequencies. A computer measures the phases of a plurality of detected image frequencies. Measurement of the particular phases of the frequency components allows determination of the image shift on the detector axis. The image shift is then used to compute angle of incidence of the light source upon the detector. The preferred embodiment employs a refractive window, hence the angle of incidence between point radiating source and mask are determined using the window index of refraction and refraction equations. Applications include within the cockpit of a jet aircraft.

Abstract: An intramedullary femoral broach aligns two instruments. A femoral neck resector guide slides over the broach and centers on the patient's femoral head to determine the height and angular rotation of resection. A circular ring of the head and cutting arms assure the system will fit any femur. A template is applied to the femoral broach and seats itself against the buttress of the broach locking it into place. The broach is then reinserted into the intramedullary canal. When the template reaches the greater trochanter the sizer is adjusted to the rotational anteversion of the canal. The handle of the femoral broach is struck with a mallet until the template is imbedded into the proximal femoral neck intramedullary bone. A retractor facilitates reaming of the acetabulum through a small anterior incision. A proximal portion digs into the bone of the superior acetabulum to allow for retraction of soft tissues.

Abstract: A protective cover is designed to be removably placed over the keyboard tray and mouse pad of a bracket system including an articulating bracket having a proximal end designed to be affixed to the undersurface of a desk top and a distal end to which the keyboard tray is mounted. The protective cover consists of a padded bag having an inner chamber sized to receive the keyboard tray and mouse pad, and a cover designed to close its access opening which consists of two flaps spaced by a recessed portion, with the recessed portion provided to allow the flaps to fold over to either side of the bracket. Each of the flaps has a releasable fastener designed to fasten the flaps in a closed configuration. Another releasable fastener is provided on the bracket and the bag so that the fastener halves can be releasably attached together to hold the bracket system in a folded configuration making it easy to transport.

Abstract: A device for controllably altering trajectory of a kicked football includes a member removably insertable in a recess of a tee. The device is used in any one of three ways. First, it may be placed within the forward recess of the tee to combine with the ball receiving recess to completely enclose the tip of the football about its periphery. Second, a protrusion of the device may be placed in front of and slightly to the right of the centerline of the football. After the football is kicked, the tip of the football strikes this protrusion, causing the football to be deflected and to hook to the left. Third, the projection is in front of and slightly to the left of the centerline of the football. After the football is kicked, the tip strikes the projection, causing the ball to travel slightly to the right.

Abstract: A room acoustic diffuser exploits interference, by reflecting waves out-of-phase with the specular energy, making it possible to diminish specular energy. This is achieved by using a diffuser based on a ternary sequence, which nominally has reflection coefficients of 0, ?1 and +1. A method for obtaining the design sequence for Quaternary diffusers is also disclosed. Also, design methods for forming the sequences into arrays, and forming hemispherical diffusers are explained.
