Abstract: A multilayer coating systems suitable for use as optical interference filters in lighting systems, for example, halogen lamps. Such an optical interference filter contains alternating layers of a high refractive index material and a low refractive index material. The high refractive index material consists of niobia, titania, and incidental impurities and contains either about 25 to less than 50 mol % titania and the balance niobia and incidental impurities, or contains about 60 to about 80 mol % titania and the balance niobia and incidental impurities.

Abstract: Reflective coating systems, methods for depositing such coating systems, and lamps equipped with such coating systems. The reflective coating systems include an intermediate metallic layer overlying a substrate and consisting of nickel, chromium or a Ni—Cr alloy, a reflective metallic layer containing silver and overlying the intermediate metallic layer, and a protective layer overlying the reflective metallic layer.

Abstract: Reflector lamps and their methods of manufacture are provided. The reflector lamp includes a parabolic housing defining an interior surface; a light source positioned within the housing; a reflector layer (e.g., including aluminum) on the interior surface of the housing; and an optical interference multilayer coating on the reflective layer. The optical multilayer coating generally includes a plurality of alternating low index layers and high index layers, with the low index layers having a refractive index that is about 1.38 to about 1.55 at 550 nm and the high index layers having a higher refractive index than the low index layers.

Abstract: Data cells traversing an Asynchronous Transfer Mode (ATM) network (10) are passively monitored by probes at two spaced points (12,14). A filtering characteristic is applied to select cells comparatively infrequently, and timestamps or sequence numbers (or both) for the cells selected at each point are forwarded to a correlator (28). The correlator identifies similarities in the temporal patterns of intervals between timestamps received from each probe, and uses these similarities to identify and correlate timestamps relating to occurrence of the same cell at the two monitored points. The correlated timestamps are used to determine parameters indicative of the performance of the network, such as one-way delay, variation in that delay, and rate of cell loss.

Abstract: A rotatable braking member, for example a disc or a drum, for a vehicle brake is provided with a separate plurality of spaced cooling fins having a co-efficient of thermal conductivity higher than that of the braking member to dissipate heat to a flowable working medium within passages between adjacent fins, and at least some of the passages are substantially uninterrupted circumferentially with respect to the direction of rotation of the braking member.

Abstract: The invention concerns disc brakes of the kind in which only one of the friction elements is directly moved into engagement with the brake disc or other rotor, the other friction element being displaced as a result of reaction forces set up by such engagement and for this purpose being carried by a caliper member which is slidable responsive to such reaction forces. In a disc brake of this type in accordance with the present invention, the caliper is mounted for sliding movement on a first pin arranged between the caliper member and a fixed torque plate member adjoining the brake disc, rotation of the caliper member about said first pin being restrained by a second pin secured to one of said members in circumferentially spaced relation with said first pin.
