Filed: 1997-10-02
Abstract: A windshield repair apparatus (20) includes a bridge (22) for holding an injector (26) adjacent to a break area (32) of a windshield (30). The bridge (22) includes a suction cup (24) for mounting the bridge (22) to the windshield (30).      The bridge (22) includes a pivotally mounted arm (50O) which allows for pivotal movement of the injector (26) away from the break area (32), and a registration system (76) which allows for accurate replacement of the injector (26) over the break area (32) following pivotal movement back toward the break area (32). A ball plunger (80) and detent mounting arrangement between the pivotally mounted arm and a remainder of the bridge (22) allows for registration. The suction cup includes a vacuum pump (90) for withdrawing air from beneath the suction cup (24). The injector (26) includes a clip securing a stopper to a body of the injector. The stopper includes peripheral lip seal at a first end of the stopper which is received by the body. The arm also is pivotally moveable toward and away from the windshield and is controlled by a threaded adjustment mechanism.

Title: Dimpled circular saw blade
Inventor: PHILLIPS GREGORY A
IPC: B23D61/12
Filed: 1997-09-08
Abstract: An improved circular saw blade having first and second planar surfaces is provided which has a plurality of dimples which formed one or both of such surfaces of the blade. The dimples each have a perimeter and include a circumferential ridge which extends above the surfaces of the body of the blade. When a side load is applied to the work piece, the ridges contact one of the walls defining the kerf being cut that is forced by the load against the blade, so that the surface of the body of the blade is spaced from the wall. The dimples are preferably formed by cold working the blade, which stiffens the blade, and reducing the vibration of the blade during the cutting procedure. The dimples and their ridges also provide greater heat dissipation, and tend to provide a laminar flow of air over the surface of the blade, acting much as the dimples of a golf ball.

Abstract: Pour résoudre des problèmes d'occupation de bandes de fréquence, dans un réseau de téléphonie avec des mobiles utilisant un protocole de type GSM, on prévoit d'utiliser une fréquence de balise unique dans une macro-cellule. Dans ces conditions, pour prendre en considération un téléphone mobile qui pénètre dans cette macro-cellule, on repère les fenêtres temporelles libres (TSi) de toutes les cellules (A-J) de la macro-cellule. Au besoin, si une même fenêtre temporelle n'est pas libre dans toutes les cellules, on fait migrer (25-27) les communications établies dans cette cellule vers une fenêtre temporelle libre dans cette même cellule, ou dans une autre cellule. Puis on attribue cette fenêtre temporelle libre au téléphone mobile entrant.

Title: Apparatus and method for a low power digital filter bank
Inventor: ZIERHOFER CLEMENS
IPC: H04R25/00
Filed: 1998-04-28
Abstract: A digital finite impulse response bandpass filter is described. Analog to digital conversion (A/D) of an input signal uses a Sigma-Delta (.SIGMA.-.DELTA.) converter, resulting in a digital sequence representation of the input signal. A low-pass FIR filter convolves the binary sequence to produce a low-pass vector, and a digital comb filter defined by at least one set of weighted and time-shifted unit impulses convolves the low-pass vector with the comb filter weights. An envelope detector detects a bandpass envelope of the digital FIR bandpass filter. Also described is a filter bank of a plurality of such digital FIR filters arranged in parallel. A square root of a sum of squares of the convolution products of the low-pass vector with the comb filter weights is calculated to estimate the bandpass envelope. The square root of the sum of two squares is estimated by determining the greater of the roots of the two squares and the lesser of the roots of the two squares, calculating a sum of one half the lesser of the roots of the two squares and one half a product of the greater of the roots of the two squares and the square root of three, and selecting whichever is larger between the greater of the roots of the two squares and the sum of one half the lesser of the roots of the two squares and one half the product of the greater of the roots of the two squares and the square root of three.
