Abstract: A touch screen device includes a display screen having a touch surface, an input knob, and a microcontroller programmed to execute a method. The knob has a stationary member with conductive base pads facing the surface and a moveable member. The knob lacks a direct electrical connection to the surface. The microcontroller receives encoder signals as the moveable member moves with respect to the stationary member, with the signals being indicative of discrete touch events between the moveable member and the screen, e.g., via an intervening switch. The microcontroller processes the encoder signals to determine a direction of movement of the knob, and derives a true position of a center point of the knob using a position of each of the base pads. The microcontroller then controls an operation of the touch screen device.

Abstract: A data module is adapted for mounting to a liquid container, such as a water bottle, a wine bottle etc., for automatically calculating or monitoring the amount of liquid dispensed from the container. The module employs a pair of metal rings which function as a sensor to activate a timer as liquid passes through an outlet opening. The data may be used to calculate the amount of dispensed liquid and may be either stored at the module and/or may be wirelessly communicated from the module.

Abstract: The nested speaker system includes a speaker unit selectively mounted inside a mounting nest. The mounting nest can be installed in various items such as coolers, bags, appliances, and furniture. The speaker unit can be interchangeably seated into various mounting nests. The speaker unit is provided with a mounting rib around opposite ends of a housing, and the mounting nest includes a corresponding mounting groove for the respective mounting rib along an interior periphery to securely seat the speaker unit when assembled. The speaker unit utilizes wireless transmissions from media players to stream audio files. Auxiliary inputs can be provided to facilitate playback of audio from other sources.

Abstract: The application discloses and claims a beverage container lid that tracks the amount of fluid consumed. The lid has a standard drinking nozzle and engagement means which includes a gasket or standard threading that sealably fit commercially available beverage containers and water bottles. The exterior of the lid has a reset button and a display window through which a display readout is visible that displays the amount of fluid consumed. The lid houses the display, a CPU, battery, sensors and internal housing through which the water flows. The internal housing has a water wheel inside of it with curved blades that are turned by the beverage as it flows out of the lid. Magnets are affixed to one or more of the blades. The CPU tracks the number of times the magnets pass the sensors and translates it into the amount of fluid consumed, which is shown on the display.

Abstract: The belt with interchangeable accessories is formed of a soft, resilient elastomer and includes a series of notches along its upper and lower edges. An accessory or accessories is/are adapted for removable and interchangeable installation on the belt. Each accessory has a pair of elastic loops extending from the back thereof. Each loop passes through corresponding notches of the belt to secure the accessory removably to the belt. The accessories may comprise a large number of different configurations, e.g., two-dimensional and three-dimensional representations, storage compartments for makeup or other purposes, mirrors or other reflective surfaces, electrically lighted displays, etc. A removable buckle is provided. The rearward portion of the buckle has a passage therethrough, the passage gripping one end of the belt therein. The overlying portion of the buckle has a channel and openable cover for removably securing the opposite end of the belt in the resulting passage.
