Abstract: Compositions and methods of using them for protecting skin, hair and nails against exposure to high energy visible light are described. The compositions can include one or more natural oils or extracts which are effective to absorb the high energy visible light at least to some degree.

Abstract: A fall control system is described. The fall control system comprises an elongate guide rail extending along an axis, one or more than one trolley for moving along the elongate guide rail, a tether attached to the trolley at a first end, a second end of the tether for attaching to a user, and a speed control system for controlling a speed of the trolley along the elongate guide rail. The speed control system comprises one or more than one speed control track attached to the elongate guide rail and extending along the axis, a background speed controller coupled to the trolley and engaged with the one or more speed control track when the speed control system or the trolley is in a travelling orientation and controlling the speed of the trolley along the elongate guide rail to not exceeded a maximum walking speed.

Abstract: A device and methods for using a device, for determining a passing of flatus is described. The device comprises a sleeve comprising a first porous gas-permeable surface, a second surface attached to the first porous gas-permeable surface defining a pocket within the sleeve, and a flatus detector inserted within the pocket of the sleeve and positioned between the first porous gas-permeable surface and the second surface. The flatus detector may be a dry-surface carbon dioxide detector that irreversibly changes colour upon contact with increased concentrations of CO2 gas, a chemiresistor, or a near field communication tag. The chemiresistor or near field communication tag may be modified for detecting target gases. The device may be a patch that is affixed to a patient or attached to a garment that is worn by the patient, or a capsule, with a detector disposed therein.

Abstract: A dimming power supply includes a power source, a transformer, a full bridge rectifier and a control switch.

Abstract: Various current controlled driver apparatuses are disclosed herein. For example, some embodiments of the present invention provide a current controlled driver including a control circuit having a current input and a driver circuit having a power input. The control circuit has an output that is directly electrically connected to an input of the driver circuit. The control circuit operates between a positive voltage level and a ground potential. The driver circuit is adapted to operate between a higher positive voltage level and a negative voltage level.

Abstract: A retracting and locking leash housing includes a casing (30) and a handle (28). A pair of connectors (32) space the casing (30) from the handle (28) and define a finger (34) opening. A trigger (38) includes a gripping portion (48) and a locking portion (46) and is slidably supported for rectilinear movement. The gripping portion (48) and the locking portion (46) are connected by arms (50), which are coextensive with the connectors (32) about the finger (34) opening. A spool (36) is rotatably disposed in the casing (30) and includes a circle of teeth (58) and a finger (34) extends from the locking portion (46) to engage the circle of teeth (58) when the trigger (38) is moved rectilinearly to a locking position to prevent rotation of the spool (36).

Abstract: A brush including removable plates with tines that can be inserted into a complementary handle. The plates, made up of tines connected to a manifold at one end, are retained by the handle. Removable flat plates can be of a unitary construction and can be rolled, stacked or folded upon one another to form layers of tines. The plates are designed to be easily separated from a brush after use to allow for cleaning or replacement. The plates may also be interconnected by a set of hinges. The tines may include a plurality of flutes or ribs that increase the surface area of the tines and aid in increasing liquid retention when the brush is being used. After use, the individual plates can be removed from the handle and easily cleaned.
