Abstract: Systems and methods for providing multiple pass continuous flow dialysis are provided. In an embodiment, a system for providing peritoneal dialysis includes a catheter in communication with a peritoneal cavity, a fluid loop in fluid communication with the catheter and capable of circulating a therapy fluid into, through and out of the patient's peritoneal cavity, a multi-line fluid circuit, the multi-line fluid circuit in fluid communication with the fluid loop and including a bypass line coupled to a discharge fluid line, and a cycler including a plurality of valves, the cycler programmed to operate the plurality of valves to selectively (i) discharge therapy fluid from the multi-line fluid circuit via the discharge fluid line or (ii) bypass the discharge fluid line via the bypass line and circulate the therapy fluid a plurality of times through the fluid loop prior to exiting the multi-line fluid circuit via the discharge fluid line.

Abstract: Systems and methods for providing multiple pass continuous flow dialysis therapy are provided. The present invention includes a fluid circuit connected to a patient via a catheter thereby defining a fluid loop along which a therapy fluid including a dialysate can be continuously circulated into, through and out of a peritoneal cavity of a patient to remove a therapeutically effective amount of excess water and solutes including uremic toxins. The feed rate and discharge rate of therapy fluid into the fluid loop can be controllably regulated in proportion to the circulation rate of fluid in the fluid loop such that the therapy fluid can pass a multiple number of times along the fluid loop prior to discharge.

Abstract: An erasing method for a non-volatile memory is provided. The method includes the following two major steps. (a) A first voltage is applied to the odd-numbered select gates of each memory row and a second voltage is applied to the even-numbered select gates of each memory row such that the voltage difference between the first voltage and the second voltage is large enough for the electrons injected into the floating gate of the memory cells to be removed via the select gate. (b) A switchover operation is performed so that the first voltage is applied to the even-numbered select gates of each memory row and the second voltage is applied to the odd-numbered select gates of each memory row such that the electrons injected into the floating gates of the memory cells are pulled away via the select gates to turn the memory cells into an erased state.

Abstract: The present invention generally relates to a method and an apparatus to detect the presence of a bacteria in a subject. More particularly, the method is directed toward the detection of a bacteria which is associated with catalyzing urea to carbon dioxide and ammonia when present in the gastrointestinal tract of a subject. The method comprises administering urea to a subject, obtaining a fluid sample from the subject after the administration of the urea and then determining the presence or amount of ammonia gas in the fluid sample. The apparatus facilitates ease of implementing the method and facilitates accuracy and speed of obtaining the test result.

Abstract: A method and system for adaptively adjusting modem operating characteristics is disclosed. A modem includes a line interface circuit and a controller. The modem is programmed (such as by user-input) with an indication of a location (e.g., country or region) where the modem is operating. When going off hook, the controller sets the modem off hook impedance to a level that would be likely to be sufficient and acceptable under applicable governmental regulations. Upon going off hook, the controller then senses the actual line voltage at the modem, and, if it turns out that the modem is not within an acceptable operating range, the controller adjusts the off hook impedance of the modem so as to bring the modem into an acceptable operating range. The invention advantageously helps reduce the need to produce numerous different versions of a given modem, instead facilitating the production of a “global” modem.
