摘要:
An optical fibre core (39) having a reflective coating (33) along a first part of its length such that electromagnetic radiation may travel along the first part of the optical fibre by means of reflection, and further having a cladding (37) along a second part of its length, the cladding having a refractive index suitable for permitting the electromagnetic radiation to travel along the second part of the optical fibre. The invention also provides a fibre optic coupling arrangement for coupling a light pipe to a clad optical fibre, the coupling arrangement comprising a light pipe comprising an optical fibre core having a reflective coating and a clad optical fibre comprising an optical fibre core with cladding surrounding the core, the optical fibre core of the light pipe being optically joined to the optical fibre core of the clad optical fibre such that electromagnetic radiation is able to travel from the light pipe to the clad optical fibre, wherein tapered cladding is provided in the region where the light pipe is optically joined to the clad optical fibre.

A non-hermetically sealed, electrochemical power source, includes a first electrode, a second electrode, a separator between the first electrode and the second electrode, and a membrane in fluid communication with an environment external to the battery. The second electrode is between the separator and the membrane. The membrane includes a first portion having a different property, e.g., density, porosity, mass transport resistance, thickness, or gas permeability, than a second portion of the membrane. Methods of designing an electrochemical cell cartridge are also disclosed.

A battery includes a battery can housing an cell that supplies electrical energy at terminals of the cell by an electro-chemical reaction with oxygen, the can including, a first member having at least one hole that is exposed to air; and a second member. The battery also includes a mechanism coupled to one of the first and second members to move the one of the first and second members such that when current is drawn from the battery, the opening in the member allows air to pass into the battery, and to move the one of the first and second members such that when current is not drawn from the battery, the opening in the member is not in registration to inhibit air to pass into the battery. The battery also includes a circuit to control the mechanism. In one embodiment the circuit monitors levels of O2 in a air plenum that surrounds the cell. The circuit to monitor levels of O2 in the air plenum includes a florescent detector/sensor that senses and responds to changes in O2 in the plenum by using the “quenching effect” of oxygen on a fluorescent material

摘要:
A method and device to prevent the refill of cartridges, including inject and laser printer cartridges. The device includes a cage made of hardened drill resistant material inserted within the central reservoir of the cartridge to prevent drilling into the cartridge. The device also includes a bit grabbing mesh designed to grab or catch any drill bit able to penetrate the drill resistant cage, thus impeding the ability of a refiller to drill holes into the central reservoir. The device also includes at least two pressure sensitive check valves that close if a refiller attempts to introduce refill ink either by forcing it in under pressure or by drawing it in by means of a vacuum created within the central reservoir. Finally, the device includes a number of packets containing an ink altering material that would be released and foul any refill ink during an attempt to refill the cartridge.
