Title: Frequency divider system
Inventor: TILLER SAMUEL A
IPC: H03K23/54
Filed: 2003-04-16
Abstract: A frequency divider circuit for providing a divided clock signal having a frequency that is an odd integer factor less than the frequency of an incoming system clock signal. The frequency divider includes a clock generator circuit coupled to a delay circuit which operates in an active and a reset phase to provide a divided clock signal from the system clock signal. In the active phase, the clock generator circuit drives the divided clock signal to a first logic state until a reset signal is received. The delay circuit then generates the reset signal at a predetermined number of system clock edges after the divided clock signal is driven to the first logic state. In the reset phase, both the clock generator circuit and the delay circuit are reset in response to the reset signal such that the clock generator circuit immediately drives the divided clock signal to a second logic state, and the delay circuit disables the reset signal within the predetermined number of system clock edges.     The delay circuit maintains a 50% duty cycle for the divided clock signal.

Patent CA-2432766-A1 (CA)
Inventor: VOCE DANIEL
IPC: H04W74/08
Filed: 2001-12-21
Abstract: An apparatus and method for optimizing multiple access satellite (Fig. 4) and terrestrial mobile communications network performance using random access or multiple access protocols such as frequency division multiple access (FDMA), code division multiple access (CDMA), or optimally, time division multiple access (TDMA). Performance is optimized through the use of persistence algorithms (830) in congestion control methods for random access channels in such a network, whereby mobile terminal participation (160) is eliminated from the control procedure. In one aspect, a fixed network (100, 120) dynamically directs the operation of a mobile terminal-based persistence algorithm using only locally derived information which is directly transformed into an accurace estimate of random access channel throughput.

Title: Stationary exercise apparatus
Inventor: RODGERS ROBERT E JR
IPC: A63B22/04
Filed: 1996-01-25
Abstract: A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints. A base frame supports a pair of reciprocating members which are displaced in a horizontal direction parallel with the floor at one end yet reciprocate in a circular motion at the other end through a coupling system attached to the frame. Structure is included which permits each foot of the user to move in a generally elliptical path during the climbing exercise. This provides for more natural movement of the knee and ankle joints minimizing unnecessary stress on the joints yet permitting a cardiovascular workout. The device may include linkage to facilitate a corresponding upper body exercise involving movement of the arm in which case each hand of the user is displaced along an arc or a substantially elliptical path, again promoting a more natural movement of the ankle, knee, elbow and shoulder joints and permitting a cardiovascular workout.

Abstract: In one embodiment, a video slot machine displays an array of symbols, and awards are granted to the player based on certain combinations of symbols across a pay line or in a pattern. While the reels appear to be spinning, or at any time prior to the final symbol display, the player may designate one or more of the positions in the array to be a special symbol. This special symbol may be a wild card, a high value symbol, a scatter symbol, a multiplier, a bonus game trigger symbol, or any other type of special symbol. The virtual reels stop rotating, and all other symbols in the array are then displayed along with the special symbol in the designated position.  The player is then granted an award based upon any winning symbol combinations as affected by the special symbol. In another embodiment, the position of the special symbol in the array is selected automatically by the gaming machine. In another embodiment, the player may identify one or more certain patterns within the array that will form a winning pattern of symbols.
