Title: Method for communicating with a voice response unit over a cellular telephone network
Inventor: KOVLAKAS STEVE
IPC: H04M17/00
Filed: 1996-12-18
Granted: 2003-11-18
Abstract: This invention overcomes the disadvantages of the prior art by providing a voice response unit that communicates rapidly and directly with a metered cellular telephone network with minimum human intervention.  The rapid communication is achieved by knowing the question or prompt posed by the voice response unit and preparing a response which is speed dialed to the voice response unit. The voice response unit also calculates a check sum to determine if there is an error in the information transmitted to the voice response unit.  The check sum may be the total of the absolute value of the request code, account number, serial number, access code and amount desired to be added to the cellular phone divided by ten.  If, the check sum calculated by the voice response unit is not divisible by ten, the voice response unit knows that the information it received is incorrect.  Then, the voice response unit would ask for the information it received to be retransmitted at adifferent rate of speed.

Abstract: A nephelometer and nephelometer/turbidimeter combination of the type useful in automated chemical analyzers is provided. The combination includes a laser for generating a polarized laser beam having an S-wave component and a P-wave component. The beam is split by a beam splitter specially constructed so that a known proportion of one of the two polarized portions of the beam is directed to a reaction container. In the reaction container, a first polarized component of the laser beam is used in a nephelometric chemical analysis. The remainder of the laser beam passes through the beam splitter to a laser control light detector. Before the remainder of the laser beam reaches the laser control light detector, however, the polarized component which is not used in nephelometric chemical analysis is filtered out. The laser control detector uses the non-filtered portion of the laser beam to control the output of the laser. The combination also includes an LED which emits a beam of light at a longer wavelength than that of the laser. Such beam of light is projected through the reaction container to a turbidimeter light detector. A second beam splitter is provided between the reaction container and the turbidimeter light detector to deflect the residual portion of the laser beam away from the laser. This prevents the residual portion of the laser beam from being reflected back into the reaction container.

Granted: 2006-10-24
Abstract: A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.
