Abstract: A solid state lamp, such as one that can replace an incandescent light bulb, has a base portion having an electrical connector for connection to a source of power, such as an Edison-type connector for connection to the mains voltage. An AC/DC converter in the base converts the mains voltage to a suitable light emitting diode (LED) drive voltage. A plurality of receptacles on the base connects to electrodes of plug-in modules. Each plug-in module supports a plurality of low power LEDs connected in series. The strings of LEDs on different modules are connected in parallel when connected to the receptacles. The modules and base are configured to allow a user to operate the lamp with different combinations of modules to generate a desired light output from the lamp. For example, the user can recreate the lumens equivalent of a 20 W, 40 W, or 60 W bulb by using one, two, or three modules.

Abstract: In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described.

Abstract: This invention concerns a method, and a device, for feedback cancellation. This invention also concerns a computer program product comprising computer program code means to make a computer execute a procedure for feedback cancellation. The method comprises providing an adaptive feedback cancellation filter which adapts under the control of a control module, and filtering at least one input of the control module to suppress correlated signals from the input prior to the control module operating upon the input. The device comprises an adaptive feedback cancellation filter, a control module and at least one filter. The control module controls adaptation of the adaptive feedback cancellation filter. The filter suppresses correlated signals from an input to the control module prior to the control module operating upon the input.

Abstract: Adaptive processing of an input signal is achieved by offline analysis, with inline processing comprising an adaptive filter. The method comprises passing the input signal through an adaptive time domain filter to produce an output signal. The input signal and/or output signal is used as an offline analysis signal. The analysis signal is transformed into a transform domain (eg frequency domain) to produce a transformed analysis signal. The transformed analysis signal is analysed, for example by ADRO, to produce a plurality of desired gains each corresponding to a respective transform domain sub-band. A time domain filter characteristic is synthesised to at least approach the desired gains. The adaptive filter is updated with the synthesised filter characteristic. Minimum phase adaptive filter techniques are found to possess particular benefits in this scheme.

Abstract: A device for separating metal components from a colloidal suspension or solution uses a vessel for holding the colloidal suspension or solution. A membrane impermeable to the selected metal components of a colloidal suspension or solution is sealed over a support to form a leaf element. The leaf element includes an outlet for the selected components of the colloidal suspension or solution and is extended into the colloidal suspension or solution. The leaf element is controllably vibrated simultaneously with application of a negative or positive pressure which is used to motivate permeation of the membrane by the liquid of the colloidal suspension or solution to purify it. Metals removed by the method include metals with an atomic number greater than 10 including and/or silicon. The colloidal suspension or solution may optionally contain a metal precipitator such as a dithiocarbamate and/or trithiocarbamate to aid in the separation.

Abstract: A support system includes a support post and support means for adjustably supporting a member to the support post. The support means includes a locking mechanism movable between a first position for press-fitting the support means, directly or indirectly, against the support post and a second position for releasing the press-fitting. The locking mechanism has a surface that abuts the support post, or a wedge member associated with the support post, when in the first position thereby to effect the press-fitting and that is released from the support post when moved to the second position to release the press-fitting.

Abstract: A medication cart also holding at least one drawer or tray and at least one bin supported on the tray containing an array of drawers and bins, and a multi-level cassette assembly. An internal locking mechanism secures the cassette assembly when it is positioned in the medication cart, and an external locking mechanism secures the cassette assembly outside of the medication cart. In addition, the cassette assembly includes a mechanism that selectably provides access to an entire tray and all bins carried in it at one time or that provides access to single bins carried on the tray one at a time. This mechanism, more particularly, (a) permits a tray to be nearly fully withdrawn from the cassette assembly thereby exposing a major portion of all carried bins to access all of their contents, and (b) permits the tray to be only partially withdrawn from the cassette assembly so that only a minor portion is exposed but such that each bin can independently be removed from the tray one at a time to access its contents.
