Abstract: A toilet for measuring excreta is disclosed. The toilet is adapted to measure the amount of excreta received by the bowl and then the flush water. A pressure sensor is configured to monitor the pressure exerted by the flush water and any excreta contained therein. Data from monitoring the pressure of the flush water and excreta therein is used to determine the weight or volume of the excreta received by the bowl. This toilet can provide data which may be used to analyze how the volume of flush water changed due to excreta deposit. A volume change feature can be associated with a urination event and the data associated with the event can be used to determine a urine characteristic of the event.

Abstract: Devices and methods for internet of things (IOT) discovery/auto discovery are described. A discovery packet is received from a device. The discovery packet includes a first stream identifier and a request to establish a second stream. A stream acceptance packet is sent to the device. The stream acceptance packet includes the first stream identifier and an input for generating a second stream identifier. A first association is added to the registration based on the request to establish the second stream. The first association is between the second stream identifier and a determined destination. A first data packet is received from the device, where the first data packet includes/utilizes the second stream identifier. The first data packet is sent to the destination based on the first association in the registration.

Abstract: A symptomatic tremor detection system is disclosed. The system includes a seat sensor to measure at least a portion of weight from a user on a seat and a foot sensor to measure at least a portion of weight from the user on a foot support while the user is on the seat and supporting a foot with a foot support. The data from the seat sensor and the force sensor is used to identify a temporary weight changes in the data which correlate with the manifestation of symptomatic tremors. An additional, or tertiary, force sensor may also be used with the system to provide additional data relevant to the detection of symptomatic tremors.

Abstract: A node and methods for securely communicating information are described. The node includes a transducer that provides a first stream of data elements, a network interface, and a microcontroller. The microcontroller identifies a first data type associated with the first stream of data elements from the transducer, harvests each data element (e.g., measurement) from the first stream of data elements based on the first data type, aggregates a plurality of the measurements into an array of first measurements, generates a payload that includes a length identifier, a data type identifier that identifies the first data type, and the array of first measurements, identifies a destination for the payload, determines a token based on the identified destination, adds the identified token to the payload to form a datagram; and sends the datagram to the destination, via the network interface.

Abstract: An analytical toilet comprising a bowl for receiving excreta from a user, a urine collection chamber for receiving urine from the bowl, a sensor for detecting properties of the urine, a valve adapted to release the captured urine from the urine collection chamber, and a source of flush water to clean the urine collection chamber.

Abstract: An analytical toilet is disclosed. The toilet includes a bowl for receiving excreta, a mechanism that uses a consumable for analyzing a sample of excreta, a storage structure for storing the consumable, a sensor that detects at least one property of the consumable, and a processor that generates an alert when the property is outside a predetermined parameter. The property the sensor detects can be used to determine at least one of the identity of the consumable, the quantity or supply of the consumable, or a property related to the suitability of the consumable.

Abstract: We disclose an in-toilet urinalysis system which includes a system for collection urine and for analysis of urine components using aptamer technology. Urine collection system may dispense urine into cuvettes, channels, or other containers that include aptamers. The aptamers may detect target molecules in urine. The aptamers may measure urine analytes, detect excreted drugs or drug metabolites, or disease markers. Upon binding to the target molecule, the aptamers may produce a signal which a sensor in the toilet may detect. In some embodiments, the signal may be electrochemical, fluorescent, or colorimetric. The measurements obtained from analysis of the urine may be used to assess a user's health or diagnose disease. In some embodiments, the measurements are stored in a controller which may transmit the measurements to a healthcare provider for assessment.

Abstract: The present disclosure relates to a method which allows direct formation of gel-like solutions of polyglucosamine at neutral pH?7 to 8, eliminating the need of prior dissolution of polyglucosamine in acidic environment; and to a homogeneous liquid combination of polyglucosamine-glyoxylate with hyaluronan.

Abstract: The present disclosure relates to a chitosan solution neutralized with amino-sugar carbonate buffering solution or amino-sugar phosphate buffering solution or phosphorylated aminosugar buffering solution. The resulting thermogelling chitosan composition is highly biocompatible, isotonic and has the ability to rapidly turn into gel upon heating to the body temperature. It provides a novel chitosan-based composition to suitable for drug delivery, cell delivery and repair or regeneration of tissues and organs as well as other clinical treatment.

Abstract: The invention is an apparatus for increasing intrathoracic pressure for resuscitating cardiac arrest patients. The apparatus comprises a flexible, substantially inelastic belt wrapped around the patient's chest and attached to a force converter. The force converter converts a downwardly directed force into a chestward resultant, which depresses the sternum, and two belt tightening resultants. The force converter comprises a pair of arm assemblies, each having a pair of spaced arms, which are pivotably mounted to a base. The base is positioned near the patient's sternum and the ends of the belt attach to one end of each arm assembly. The opposite, handle ends of the arm assemblies are depressed toward the chest causing tightening of the belt and compression of the chest cavity.
