Abstract: A sensor device includes a signal transmitting component configured to transmit a signal into a container engaged by the sensor device, wherein a frequency of the signal is selected to allow the signal to at least in part pass through a content fouling at least a portion of the signal transmitting component. The sensor device includes a processor configured to process a received reflected version of the transmitted signal to determine an identifier associated with an amount of content in the container engaged by the sensor device. The sensor device includes a wireless transmitter configured to transmit the identifier associated with the amount of content in the container.

Abstract: A network connection is established with a server. A broadcasted advertising packet of a wireless communication protocol is received from a remote device. The remote device repeatedly broadcasts content of the advertising packet based at least in part a total number of remote devices specified to broadcast to the system. Payload content from the advertising packet is extracted. At least a portion of the extracted payload content is sent via the network connection to the server.

Abstract: A system and method are disclosed for quantity analysis. A quantity identification of an amount of content included in a container is received from a container cover of the container. The quantity identification is analyzed along with a history of past quantity identifications received from the container cover over time to determine an analysis result. An action associated with the content of the container is performed based on the analysis result. A system and method are disclosed that include one or more devices that help users track remaining quantity and expiration of food (e.g., including beverages).

Abstract: A measurement device includes a transmitter configured to transmit an interrogation signal. The measurement device also includes a receiver configured to receive the interrogation signal that has been reflected within a container. The received reflected interrogation signal corresponds to a fill level of the container. A protective barrier covers at least the transmitter or the receiver. If the protective barrier covers the transmitter, the transmitter transmits the interrogation signal through the protective barrier and the transmitter and the protective barrier are separated by a gap.

Abstract: An identity of a container coupled to a content level sensor device is received. A plurality of signal parameters associated with the container is identified. The signal parameters are transmitted to the content level sensor device, wherein the signal parameters are indexed according to a level of content in the container.

Abstract: A measurement device includes a sensor configured to detect triggering of the device. The measurement device further includes a transmitter configured to transmit an interrogation signal in response to the triggering of the device, and a receiver configured to detect a received signal that captures one or more reflections of the interrogation signal. A processor of the measurement device is configured to select a selected reflection among a plurality of identified potential reflections captured in the received signal, and provide an identifier corresponding to the selected reflection that is associated with an amount of content included in a container engaged by the content measurement device.

Abstract: A sensor device includes an interrogation signal transmitter configured to transmit an interrogation signal to determine an identifier associated with an amount of content included in a container engaged by the sensor device. The interrogation signal transmitter is configured to transmit the interrogation signal that travels through air included in the container to reflect off the content in the container.

Abstract: A sensor device includes a communication transmitter configured to transmit a sensor device identifier. The sensor device includes a communication receiver configured to receive a sensor configuration associated with the sensor device identifier. The sensor device includes an interrogation signal transmitter configured to transmit an interrogation signal based at least in part on the received sensor configuration to determine an identifier associated with an amount of content included in a container engaged by the sensor device.

Abstract: A content fill level sensor is disclosed. The sensor includes a transmitter located proximal to a portion of a container cover that is configured to engage an opening of a container. The sensor also includes a waveguide extending from the transmitter such that the waveguide includes a distal end that is configured to be located within an interior of the container when the container cover engages the container.

Abstract: A portable drum that includes a drum head and a detachable drum shell, where the drum head may include an upper drum head and a detachable lower drum head and the drum shell may include one or more detachable sections. Once assembled, the upper drum head, the detachable lower drum head, and the sections of the drum shell may be held in place by a tensioning system that may include vertical straps and a waist belt strap. The portable drum may be disassembled and placed in a travel mode by nesting the sections of the drum shell in the lower drum head, and then placing the lower drum head into the upper drum head.

Abstract: A self-tightening device for fastening two structures together includes a female component and a male component where the female component is capable of receiving the male component. The female component includes a moveable member, an energy storing mechanism and a retaining mechanism. The movable member is movable between an unlocked position and a locked position. The energy storing mechanism has stored energy for causing the moveable member to move from the unlocked to locked position when the energy in the energy-storing mechanism is released. The retaining mechanism holds the energy-storing mechanism in the stored-energy state until the retaining mechanism is released.

Abstract: A fluid dispenser is disclosed having a storage chamber for storing a liquid, a collection assembly for collecting a portion of liquid, a pump assembly, and a tube extending from within the storage chamber to within the collection chamber through which the portion of liquid is pumped into the collection assembly. The pump assembly includes one or more pump actuators, and the fluid dispenser may have multiple storage chambers, each having a corresponding tube. In addition, the fluid dispenser may have multiple collection chambers. The pump actuators may be, for example, a flexible diaphragm or a trigger-actuated pump mounted on the side of the fluid dispenser The pump mechanism may be incorporated into the capillary, and it may be, for example, a piston pump or any other type of pump known in the art.
