Abstract: A portable chair assembly including first and second chairs and a movable support frame, each chair having a seat and a backrest. Each backrest is adapted (i) to be folded by a user onto its respective seat in a collapsed position and (ii) to be moved away from that seat into a deployed position. The support frame has at least two frame segments, each frame segment having an upper frame portion supporting one of the backrests at pivotable connections with the upper backrest portion of that backrest, and each frame segment being joined to the other frame segment by an upper joint member and a lower joint member. At least one angle member is provided per chair, a backrest end portion of each angle member being fixedly or removably secured to one of the first chair backrest and the second chair backrest, and a frame portion of each angle member restricting movement of the support frame away from the seats to establish a maximum deployment angle in the deployed position.

Abstract: A modular toy construction system, comprising: a plurality of interactive toy construction elements, each interactive toy construction element comprising a sensor and/or a function device, the function device operable to perform a user-perceivable function; each interactive toy construction element further comprising a first communications circuit configured to wirelessly communicate signals and to wirelessly harvest energy for operating the function device and/or the sensor.

Abstract: An underwater grenade and a method for using an underwater grenade. A depth activated, hand emplaced ordnance utilizing safe and arm technology to address underwater threats (such as enemy swimmers) while providing a safe interface with personnel. The grenade is armed after a sequence of events have occurred including reaching a desired depth and a desired passage of time. Failure of any of the events to occur will cause the grenade to be rendered safe.

Abstract: The present invention provides a sports toy with multiple instructional modalities which combine auditory, visual, and kinesthetic stimulation to teach and reinforce language skills. In one embodiment, a sports toy comprises a goal defining an aperture and a switch associated with the goal for indicating that a goal has been scored. A memory is operatively associated with the switch. A voice synthesizer is operatively associated with the memory and a speaker is in turn operatively associated with the voice synthesizer. Code stored in the memory causes sounds associated with language to sound from the speaker after the switch is activated. The sounds associated with the language include letter names, letter sounds, words, or phonics. The sports toy may also comprise an electronic visual display operatively associated with the memory for displaying stored images, such as letters or words, after the switch is activated.
