Abstract: Method of determining whether a balloon of a balloon catheter is positioned in the stomach of a person. The balloon catheter comprises a catheter and a balloon. The method comprises the steps of: a) inflating (1401) the balloon and determining (1402) a pressure inside the balloon, until at least one of the following conditions is satisfied: (i) a predefined target volume is inserted in the balloon, and (ii) the determined pressure is larger than a threshold: b) testing (1403) whether the determined pressure (p) is or was larger than the threshold, and if so, deflating (1405) the balloon; and if not, providing (1406) a signal indicative of correct positioning of the balloon catheter. A system comprising a balloon catheter (130), and an inflation device (113), and a pressure sensor, and a control unit (110) for performing such a method, and optionally a food pump (112).

Abstract: A balloon catheter (100), suitable for delivery of a balloon to the stomach via application by the nose, the balloon catheter comprising a catheter (2) and one or more inflatable balloons (1) fixedly attached to the catheter. The balloons have an outer diameter from 4 to 7 cm, are made of a relatively hard material (e.g. durometer 70 to 100 shore A), and have an effective length of 7 to 18 cm or a total inner volume of 90 to 330 ml, when inflated by 0.2 psi. A system comprising the balloon catheter, and a pressure sensor for measuring a pressure of a fluid inside the balloon, and optionally a fluid pump for inflating and/or deflating the balloon, and a control unit for reading the pressure sensor and optionally for controlling the fluid pump.

Abstract: A system (100) for artificially feeding a patient, comprising: a pressure sensor (114) fluidly connectable to an inflatable balloon (B) via a first lumen of a balloon catheter (130); a controller (110) operatively connected to the pressure sensor (114) for obtaining the measured pressure values; a food pump (112) fluidly connectable to a second lumen of the balloon catheter having at least one opening (132) for providing food; the controller (110) operatively connected to the food pump (112) for driving the food pump at a configurable flow rate; wherein the controller (110) contains computer executable instructions comprising: first code fragments for performing a first algorithm (1300) for extracting gastric motility information from the measured pressure values, and second code fragments for performing a second algorithm for dynamically adjusting (708) said flow rate based on said extracted gastric motility information.

Abstract: Articles and methods for transaction irregularity detection are disclosed. In one example, the article discloses: a memory including a record of a last-reported security-device transaction with the security-device, and including a last-reported transaction counter value associated with the last-reported security-device transaction; a previous device identifier; a record of the previous security-device transaction with the security-device, and including the previous device identifier associated with the previous security-device transaction; a record of a current security-device transaction with the security-device, and including a currently-reported transaction counter value associated with the current security-device transaction; and a back-end device tagging the previous device with fraud if the current transaction counter value differs from the last-reported transaction counter value by other than an increment.

Abstract: The disclosure relates to dynamic secure messaging using near-field communication. Example embodiments include a near field communication target device (102) configured to respond to a read request (202) transmitted by a reader device (101) by transmitting a message (204) comprising an unencrypted portion and an encrypted portion, the encrypted portion incorporating a counter that is incremented each time a read request is received.

The flange pin has a portion extending outwardly beyond the end plate and provided with at least one arresting opening. The connector has a toggle lever-like bridge web extending between the plate-shaped legs and provided with a threaded opening.
