摘要:
A ball having an inflatable ball shell within which is found an inflatable inner ball partially filled with an inner ball gas and partially filled with a liquid that is held in the center of the inflatable ball shell by an inflatable support when the inflatable inner ball, the inflatable ball shell and the inflatable support are inflated. The ball exhibits an eccentric and unpredictable motion unless a concomitant spin is appropriately applied to it and the motion of the ball is primarily determined by movement of the liquid within the inflatable inner ball. The inflatable support can be a donut-shaped chamber having an inner radius which is substantially the same as, and may be attached to, an outer radius of the inflatable inner ball. Alternatively, the inflatable support can be three or more elastic spherical shells attached to the inflatable inner ball.

A method for reducing the cost of demand control ventilation applications deploys wireless CO2 sensors inclusive of relative humidity and temperature throughout an indoor space without the need for wiring while utilizing the license-free 902-908 MHz ISM band by use of a Sequential Transmission Asynchronous Reception System (“STARS”) that is software controlled.

The concentration of a gas species is detected by using a single beam NDIR gas sensor in which an infrared source element is driven at two different temperatures, a feed back loop senses an operation voltage of the source, a differential gain amplifier creates a high cycle amplified output during a high cycle and a low cycle amplified output during a low cycle while a controller synchronizes the source driver so that a signal processor can determine the gas concentration through use of the high cycle amplified output and the low cycle amplified output. The infrared source can be a non-genuine blackbody source such as an incandescent miniature light bulb when the sample chamber is a thermally insulated aluminum tube that is maintained at a preselected temperature greater than ambient so that the glass envelope of the bulb is maintained at an equilibrium temperature (such as approximately 30 degrees Celsius plus or minus two degrees Celsius) during its low cycle operation state.

Multiple secure transactions are provided through use of a method that uses customer one-time unique purchase order numbers (“Coupons”) generated by an algorithm that uses a permutated user key and a user insertion key as input variables. A user key (such as a Personal Identification Number, or “PIN”) is combined with a permutation variable that is correlated with a customer sequence number to create the permutated user key. A random number generator is used to generate the user insertion key correlated with the customer sequence number. The algorithm can insert the permutated user key into a user account number through use of the user insertion key. A Coupon is validated by confirming that it is contained in a set of money source Coupons generated by a money source using the user key and a random number generator that is synchronized with the random number used to generate Coupons. Once a Coupon is validated, the matching money source Coupon and all earlier generated money source Coupons are deleted from the set, and a new set is generated. If a preselected number of Coupons are not validated for a chosen entity, an invalid user account number will be set. Coupons can be used for credit card or bank card transactions, and they can be generated without changing fixed digits of traditional twenty digit account numbers.

An East-West casino offers two or more gambling games in which one is a poker game using a traditional Western deck of cards and another is a poker game based upon a new Chinese Poker Deck of cards.
摘要:
An NDIR gas sensor and methodology use an absorption bias between signal and reference outputs to determine sample concentration of a gas being measured. The absorption bias is created by using a signal channel in a sample chamber with a signal path length that is greater than a reference path length of a reference channel in the sample chamber while both the signal and reference detectors have an identical narrow band pass filter with the same Center Wavelength (“CWL”), Full Width Half Maximum (FWHM) and transmittance efficiency at the CWL. Performance is improved when the reference detector and the signal detector share a common thermal platform that can also be shared by the sample chamber and the infrared source.
摘要:
A method of playing a community card poker game in which two down cards are dealt to each player from a deck having suited cards, non-suited cards and a wild cards, followed by a betting round, then three community cards are dealt face up followed by a betting round, then a fourth community card is dealt face up followed by a betting round and a final card is then dealt followed by a final betting round, a winning hand is then declared and wagers are settled. The winning hand can only contain one wild card and if a player cannot make a hand with only one wild card (because the player has too many wild cards), the player's hand is declared a losing hand. A betting variation is that a losing calling party pays a penalty in some circumstances based upon the ranking of the winning hand.
摘要:
A fresh air controller interfaces directly with the electromechanical circuit of an air-conditioner to control its operating settings based upon detected Carbon Dioxide (CO2) level in Parts-Per-Million (PPM) using a “Capno-Switch” which is in essence a specially designed single-beam NDIR CO2 sensor enhanced with features and specifications to render it rugged, compact and very low-cost; unlike conventional single-beam NDIR CO2 sensors, the “Capno-Switch” is capable of providing long-term stability and accuracy in CO2 measurements. The operating settings it can control for the air-conditioner include 1) shutting off the fan, cooling unit and fresh air damper to save energy when the detected CO2 level in the cold air duct is less than 600 PPM; 2) turning on only the fan when the CO2 level is between 600-1,000 PPM; 3) turning on both the fan and the cooling unit when the CO2 level is between 1,000-2,000 PPM and 4) starting to open the fresh air damper to let fresh air in when the CO2 level is in excess of 2,000 PPM. With the incorporation of the “Capno-Switch” as a fresh air controller, air-conditioners can now provide good indoor air quality while at the same time save energy by effectively shutting itself down when nobody is detected to be present.
摘要:
A method for detecting the concentration of one or more gas species by using infrared radiation emitted from one or more sources into a sample cell which is a hollow waveguide with multiple bends collectively greater than 180 degrees in three dimensions, the infrared radiation being quasi-focused into a beam with an angle of incidence between greater than approximately 0° and approximately 10° relative to a longitudinal axis of a first linear segment of the sample cell proximate the source, then detecting two or more signals in which one of the signals is used to compensate for water vapor. The methods can detect gas concentrations down to 1 ppm or less.
