A Braille pin has three parts sharing a common longitudinal axis. A first part has a first breath and includes a rounded tip felt by a user. A second part has a noncircular transverse cross-section and has a breadth greater than the first breadth. A first shoulder is formed by the juncture of the first and second parts. A third part has a third breadth less than the second breadth. A second shoulder is formed at the juncture of the second and third parts. A pinhole has first, second, and third s...

An improved hose clamping device which uses a housing with a flexible band extending therefrom, and a cylindrical roller with outwardly protruding spiked elements, the roller rotatably mounted within the housing. A turning mechanism turns the roller and the flexible band engages the spikes on the roller to be drawn forward into and through the housing. The band is ideally constructed in whole or in part of a strong fibrous mesh, such as Kevlar, which facilitates ready engagement with the spiked ...

A pager includes a belt clip for securing the pager to another object, and a leaf spring for attaching the belt clip and pager housing together while providing a decreasing force between the belt clip and pager housing as the belt clip is opened.

An electronic device (100) includes a housing (222) and a piezo-bender (400). The piezo-bender (400) includes a metal beam (402) having at least a portion of a surface mechanically coupled to a piezo-ceramic layer (304). The piezo-bender (400) is flexibly coupled to the housing (222) at an end of the metal beam (402) forming a cantilever structure. A vibratable body (404) is mechanically coupled to the other end of the metal beam (402). A tuning slide (604) is slidably coupled to the piezo-bende...

A clasp (200) for securing first and second wrist straps (112, 114) including a base member (202) and a pair of sides (204, 206) contiguous with the base member (202). A first compression member (208) located between the pair of sides (204, 206), the base member (202) and the first compression member (208) for engaging the first wrist strap (112) slidably therebet...

A hinged device (100) comprises a first body portion (105) having a first end (115), wherein the first end (115) is substantially cylindrical and curved about a first axis, and wherein the first end (115) has a first plurality of cogs formed thereon substantially parallel to the first axis. The hinged device (100) further comprises a second body portion (110) having a second end (120), wherein the second end (120) is substantially cylindrical and curved about a second axis, and wherein the secon...

A protective pouch (26) for storing eyeglasses (24) or small objects such as keys or money that can be rolled up into a compact configuration (44). The pouch is provided with an eyeglass strap (21) with ends (20) capable of releasably attaching to the eyeglass arms (22) so that it is always available for use and cannot be lost. The two ends of the strap pass through holes (25) into the interior cavity (46) of the pouch, pass out the open end (48) of the pouch and are attached to the eyeglass arm...

A housing (12) for a portable electronic device (10) has a battery compartment cover (14) and a latch (20). The latch has a cantilevered beam (42) that rotates about a base (40) fixed to the housing. The cover has a notch (38) on an inner surface (36). An engagement end (44) of the cantilevered beam rotates into the notch for securing the cover to the housing. Application of an external force on the cover approximately opposite the latch in a direction toward the latch causes the engagement end ...

An impact resistant switch mechanism is disclosed which includes a switch disposed within a housing of a device, such as a communication device or the like. The housing has an opening formed therein through which the switch may be operated from outside the housing. An extension of material extends from the housing about the housing opening, and a shaft extending through the extension of material and the housing opening is coupled at one end to the switch for operation thereof. A knob is attached...

A vibrator (2) comprising: a massive, magnetic member (16) arranged for movement about a reference position; and electromagnetic actuator means (12) for causing said member to move; and magnetic suspension means (8, 10) arranged on either side of said member for suspending said member therebetween.
