Abstract: A system for disposing of medical waste is generally configured to sort waste items into a plurality of containers according to applicable rules and regulations governing the handling and/or disposal of such items. In one embodiment, at least one of the medical waste items is a regulated drug that is regulated by, for example, the Drug Enforcement Administration (DEA). The regulated drug is inaccessible once disposed in the container. In some embodiments, a system comprises sorting stations each of which houses a number of disposable containers. Each station can identify an item of waste, determine the most appropriate container for the item, and facilitate disposal of the item in the appropriate container. In some embodiments, a detection system for determining a presence and/or a quantity of waste items within a container is also provided. In some embodiments, access to discarded waste items is restricted once the waste items have been placed in a container.

Abstract: Systems and methods for analyzing the jitter content of an oversampled digital communication signal are disclosed. Advantageously, the communication signal can correspond to an arbitrary data sequence, rather than only to a repeating test sequence. For example, the systems and methods can be embodied in test equipment and in simulation equipment as design tools and/or validation tools. The systems and methods disclosed advantageously facilitate the decomposition and quantification of the main jitter components (random and deterministic), as well as its various subcomponents (periodic jitter, data-dependent jitter, inter-symbol interference, device-state-dependent jitter, other bounded uncorrelated jitter, and data-dependent-random jitter).

Abstract: This invention provides a method for commissioning an optical network using internal Automatic Spontaneous Emission (ASE) light inherently present in the optical network as a light source (the ASE light source) for measuring losses inside and between nodes in the network. A modular segmented approach is adopted and the network is commissioned segment by segment. The method uses techniques for the correction of the Optical Signal to Noise Ratio induced error as well as the Spectral Filtering Error during the loss computation required for adjusting the gains of the amplifiers at each network node to an appropriate value. Since the method does not require an external laser source that needs to be moved manually from node to node, it greatly reduces the commissioning time. Since it uses only the existing components of the network nodes it also leads to a significant saving in cost.

Abstract: Identification of optical channels in wavelength division multiplex (WDM) optical networks may be confounded by unwanted noise tones interfering with pilot/dither tones used for identifying optical channels. The invention describes a method of selecting pilot/dither tones that are selectively restricted to avoid allocating dither/pilot tone frequencies that appear as noise tones along the path of an optical channel in the optical network.

Abstract: A failure protection between interconnected adjacent Resilient Packet Rings (RPRs) in a multiple RPR network is provided. Two paths, a regular message path and a protection path, are provided between two adjacent RPRs. The regular path is used for routing inter-ring messages when no failure has occurred on the path. Messages are rerouted through the protection path when a failure occurs on the regular path. Each of these paths has two RPR interface nodes (one for each RPR) that are connected to an interconnection device (a layer 2 bridge or a layer-3 router) through interconnection links. Procedures for detecting failures and generating notifications for message rerouting and fault reports are executed at the interconnection devices. The procedures use periodic keep alive messages for diagnosing network segment and interconnection device failures. The fault detection and message rerouting are accomplished in less than 50 ms.

Abstract: A method and apparatus for identifying user gesture includes a touch sensor for determining contact information that describes locations at which a user contacts a touch sensitive surface corresponding to a display. The touch sensor provides the contact information to a gesture identification module which uses state information to identify a user gesture and, responsive thereto issues an associated display command to a display control module. The display control module updates the display based on display commands received from the gesture identification module.

Abstract: A printhead carrier includes a body defining a receptacle for receiving a supply cartridge. The body includes a front portion, and a rear portion spaced from the front portion. The rear portion has a latch opening. A cover is provided having a first end configured for pivotal attachment to the front portion of the body. A latch arm has a proximal end attached to the cover. A distal end of the latch arm includes a latch lip. The latch lip engages the latch opening in the rear portion of the body when the cover is in a closed position. A release mechanism is coupled to the rear portion of the body. The release mechanism includes a cam for engaging the latch lip of the latch arm to force the latch lip out of the latch opening when the release mechanism is moved from a latch position to a latch release position.

Abstract: A multi-stage method and apparatus for determining a faulty component location along an optical path through an optical fiber in an optical network are disclosed. A total power of the optical fiber, and a total wavelength power as a sum of powers of the individual wavelengths at a plurality of local detection points are measured and compared at the local detection points, followed by determining whether or not a faulty detection point exists along the optical path. If a fault is identified, the method provides a multi-stage fault detection procedure, including measuring a total wavelength power loss between a local detection point and an adjacent detection point, between the local detection point and multiple non-adjacent detection points, and a correlation of the measured total wavelength power losses between the various detection points. A corresponding apparatus for determining the faulty component location in the optical network is also provided.

Abstract: A method and system for compensating for side effects of cross gain modulation in amplified optical networks, which allows reliable identification of expected and unexpected channels in the network is provided. Each optical channel traveling in the optical network is marked with a unique channel signature (expected channel signature), having one or more dither tone modulated onto the optical channel; followed by detecting a spectrum of tones, including said modulated dither tones and ghost tones thereof produced by the cross gain modulation in the optical network, at various locations in the optical network. Amplitudes of the spectrum tones, which belong to the expected channel signature, are compared with a first threshold, while amplitudes of the remaining spectrum tones, which are not the valid tones, are compared with a second threshold, which is lower than the first threshold.

Abstract: Optical interconnects and methods for wavelength management are provided to interconnect optical rings while overcoming color-blocking and allowing for wavelength re-use within optical rings. The optical inter-connects having a wavelength selective element such as a reconfigurable add/drop demultiplexer (ROADM) and a band-modulo demultiplexer having a free spectral range (FSR) combined with a pool of wavelength conversion resources. More flexible interconnect systems can use a photonic cross-connect (PXC) to allow sharing of a pool of wavelength conversion resources among several optical rings.

Abstract: Methods and devices are provided for optical demultiplexing and optical multiplexing. An optical wavelength demultiplexer adapted to perform wavelength demultiplexing of an input optical signal containing a plurality of wavelengths is provided. A tuneable filter in combination with a device with a required free spectral range results in a tuneable demultiplexer arrangement which eliminates the need to inventory large numbers of different demultiplexers. Similarly, tuneable lasers in combination with a device with a required free spectral range result in a tuneable multiplexer arrangement.
