Abstract: This invention comprises a flexibly-resilient system of lighting that spans a bilateral safety zone around a bicycle in the upper-rear quadrant of space around the bicycle that can be clearly seen by the driver of a vehicle approaching the bicycle from the rear. This invention can help to prevent bicyclists from being hit by a vehicle from behind during the evening or at night, especially when a bicyclist is stopped at an intersection. This bicycle lighting system may also prove useful for reducing the chances of bicyclists being hit by vehicles that are turning right at an intersection, at any time of the day. This invention corrects many of the limitations of the prior art and can be a significant advance in bicycle safety.

Abstract: This invention is a sound-insulating enclosure that contains at least one bed, in which one or more people sleep, wherein the configuration of this enclosure automatically changes from a more-closed configuration to a more-open configuration over time, or vice versa. These changes in configuration can be in response to sounds or can occur in a pre-programmed manner.

Abstract: This invention is a wearable device that masks and/or cancels annoying ambient sounds to help a person sleep. It includes a soft and stretchable member, such as a headband or hat, that contains one or more sound-conducting tubes. Sound that is emitted from the one or more tubes helps to mask and/or cancel annoying ambient sounds. Advantages of this device over prior art include: no speakers or other rigid components over a person's ears that can be uncomfortable or unsafe when the person sleeps on their side; a relatively wide sound-emitting area to accommodate different size and shape heads; and a stretchable wearable member that gently clings to the person's head to avoid having sound-emitting areas shift away from the person's ears as they toss and turn in their sleep.

Abstract: There is a growing need for safe methods to insulate sleeping people from intrusive environmental noises so that they can get a decent night's sleep. This invention solves the problem of how to provide a sleeping enclosure with a high degree of insulation against environmental noises while also providing assured ventilation within the enclosure. It features an active ventilation means and a passive ventilation means that are physically linked so that there is always one of them providing ventilation. This linkage combines the superior sound-insulating properties of active ventilation (such as a longer air conduit for reduced intrusion of environmental noises into the enclosure) with the superior safety properties of passive ventilation (such as not being vulnerable to power failure or mechanical failure).

Abstract: This invention is dental floss or dental tape whose cross-sectional size can be adjusted after it is inserted into the proximal space. This is accomplished by making floss or tape with two or more members, wherein longitudinally pulling a subset of those members relative to the other members increases the cross-sectional size of the floss or tape. The size of the floss can be optimally adjusted to match the size of the interproximal space and clean the space most efficiently.

Abstract: This invention uses hydraulic or pneumatic passageways to create a wearable, portable, washable, and relatively unobtrusive device for efficiently converting movement of a relatively large portion of the human body into electricity. This device comprises: a flowable substance; passageways through which the flowable substance flows that are worn over the exterior of the human body; and energy-converting members that convert the energy of the flow of the flowable substance into electricity.
