Abstract: A portable light may comprise: a light housing having housing parts for enclosing a source of electrical power and supporting an electrical light source, a slide latch slidable on the light housing parts between latched and unlatched positions; a projection proximate the slide latch when the housing parts are adjacent; wherein when the slide latch is moved to the latched position, separation of the housing parts is prevented, and wherein when the slide latch is moved to the unlatched position, the housing parts can be separated. A tool may be needed to open the housing.

Abstract: A sleeve for a portable light may comprise: a hollow sleeve for surrounding a source of electrical power and having a plurality of elongated longitudinal spring members. Only one end of each spring member is connected to a wall of the hollow sleeve and an opposite end thereof is free. Each spring member is formed to partly extend radially outward of the hollow sleeve and to partly extend radially inward of the hollow sleeve toward a source of electrical power that may be disposed therein. The hollow sleeve may be disposed in a portable light that may include a housing, a light source and a source of electrical power that may reside in the sleeve.

Abstract: A portable light may comprise: a light housing for enclosing a source of electrical power and supporting an electrical light source, a face cap rotatably mounted to the light housing. The face cap may have one or more lenses positionable in front of the electrical light source. A light source control circuit interior the light housing has at least one switch actuator for selectively energizing the light source, and an actuator member of the face cap. Rotating the face cap moves the actuator member into a position to actuate the switch actuator, whereby rotating the face cap produces the selective energization of the light source. The portable light may require a tool to open the housing, e.g., to replace the source of electrical power and/or may be pivotably mounted to a light base.

Abstract: In an adjustable light, a mounting base is formed with a pair of arcuate slots for receiving hooks protruding from a light module. For attachment of the light module to the base, the hooks enter open ends of the respective slots, and the light module is rotated to engage the hooks with the slots. A sheet of spring metal with two series of protrusions is sandwiched between a rear part of the base and a front part in which the slots are formed. The protrusions are exposed through the slots, and a space is provided behind the protrusions, allowing them to move resiliently when engaged by the hooks as the light module is rotated so that the light module can be retained in any selected one of a plurality of angular positions.

Abstract: In a personal headlamp, a housing, containing both an illumination source and a power source, is mounted in cantilever fashion on a bracket that comprises a back part and a collar fastened to, and extending forward from, the back part. A resilient pawl, which extends from the back part through a slot in the collar, is engageable with any selected one of a series of circumferentially spaced notches formed on a ring-like protrusion on the housing that fits rotatably into the collar.

Abstract: A fetal electrode product for transmitting signals indicative of fetal heart rate from a fetus to a monitor. The product includes a slotted introducer which can be comfortably inserted through the cervix of the mother. A drive mechanism slides and rotates a holder--to which are attached, at opposite ends, a fetal spiral electrode (FSE) and a reference electrode--within the introducer to secure the FSE to the fetus. The solid drive mechanism has a drive rod, a handle on one end of the drive rod imparting translation and rotation to the drive rod, and a clutch on the opposite end of the drive rod imparting translation and rotation to the holder. The drive rod, handle, and clutch each have a channel transporting a twisted wire strand from the electrodes to a connector. The connector has an outside dimension greater than the inner diameter of the introducer to facilitate manipulation.

Abstract: A fetal electrode product for transmitting signals indicative of fetal heart rate from a fetus to a monitor. A drive mechanism slides and rotates a holder--to which are attached, at opposite ends, a fetal spiral electrode (FSE) and a reference electrode--to secure the FSE to the fetus. The drive mechanism has a solid drive rod, with at least two regions of different diameter defining the torque versus angular deflection characteristics of the drive rods and a clutch connected to the drive rod and imparting translation and rotation to the holder. The clutch is sufficiently pliable to slip over the reference electrode when the holder resists rotation. The drive rod, a handle, and the clutch are integrally molded together to form the drive mechanism and each has a channel transporting a twisted wire strand, which includes an untwisted length to facilitate removal of the FSE from the fetus, from the electrodes to a connector.

Abstract: A packaging system for a fetal electrode assembly. The assembly includes an electrode which can be attached to a fetus. The electrode is coupled to an electrode wire. The electrode wire extends through a drive tube and terminates in a connector end. A flexible guide tube receives the drive tube. The packaging system includes a handle and a clip. The handle is attached to the rearward end of the drive tube. The handle has a forward section which detachably mounts inside the rearward end of the guide tube. The handle also has a passage for receiving the connector end and a slot for securing the electrode wire when the electrode is not in use. The electrode projects from the forward end of the guide tube when the forward section of the handle is mounted inside the rearward end of the guide tube.
