Abstract: A sensory transmitting membrane device having a flexible base material including a plurality of solid or hollow projections integrally connected thereto and extending from opposite sides of the membrane. The projections on one side of the membrane are offset from the projections on the opposite side of the membrane and are positioned so that an edge of the base of a projection on one side of the membrane is in proximity to the opposite edge of the base of a projection on the other side of the membrane, whereby a linear motion of one projection in a direction parallel to the membrane results in a similar motion by any cooperating projections, to thereby enhance the transmission of tactile sensations from one side of the membrane material to the other side. The sensory transmitting device is particularly useful in latex or rubber surgical gloves, finger cots or condoms.

Abstract: A device for the transmission and enhancement of tactile sensations transmitted across a barrier membrane, particularly condoms, finger cots and gloves used to prevent transmission of disease organisms between contacting body tissues. The device has a plurality of antipodal pairs of projections extending through the barrier membrane whereby the barrier membrane acts as a fulcrum for the transmission of movement by one projection of an antipodal pair to the other member of the projection pair.

Abstract: An insolation survey device for determining the exposure of a reference point to a cyclically varying radiation source. The device employs a base member for horizontally supporting a display sheet premarked with a grid calibrated in units corresponding to the measurement being taken. A transparent reflective member is supported by the base member over the display sheet so that a reflected view of the surrounding appurtenances and the view of the display sheet, through the transparent dome, form one composite picture. In the composite picture so formed, the period or periods, if any, within the radiation cycle that the reference point will be exposed to said radiation appear as unobstructed sky superimposed onto the premarked grid. A compass is provided to directionally align the device and means are provided for orienting the base member in a true horizontal plane.
