Abstract: An illumination system (10), comprising:—four lamps (12A, 12B, 12C, 12D);—four lamp drivers (13A, 13B, 13C, 13D) capable of driving their corresponding lamps with respective dim factors (?1, ?2, ?3, ?4);—a common controller (15) for controlling the dim factors of the respective lamps. The controller is responsive to an input signal indicating a target color point (T) having target chromaticity coordinates (xT, yT) and target brightness (BT). The controller sets the dim factor (?4) of one lamp to be equal to 1, and calculates an optimum solution for the other three dim factors as a function of the target chromaticity coordinates (xT, yT), for the maximum allowed value of the luminance (YMAX) for which 0???1 applies for each of said dim factors (?1S, ?2S, ?3S).

Abstract: A wireless light sensor, being part of a lighting system, has a sensor element generating a light measuring signal, a microcontroller coupled to the sensor element, and a radio communication device coupled to the microcontroller. The microcontroller has an active mode and a sleeping mode. The light sensor further has a wake-up circuit which determines a rate of change of the light measuring signal, when the microcontroller is in the sleeping mode. The wake-up circuit brings the microcontroller from the sleeping mode into the active mode, when the rate of change of the light measuring signal exceeds a predetermined threshold.

Abstract: An apparatus for preparing a syringe for use in injecting a medication includes a body extending obliquely upwardly, with a carriage slidably secured thereto and adapted to support a syringe. The syringe is fixedly secured to the body, and translation of the carriage proximally and distally knocks off the needle protective cap and the plunger cap. A trough aligned with the syringe enables an injectant vial to be translated downwardly to drive the needle into the vial. A plunger driver is slidably mounted on the body to engage the syringe plunger and assist its withdrawal and retraction. A protective cap holder may be placed on the trough to engage and remove the protective cap for later use.

Abstract: A lamp driver circuit (400) comprises a feedback circuit for controlling stable operation of a discharge lamp (La), e.g. an inductively coupled discharge lamp such as a molecular radiation lamp, and for controlling a light output level of the discharge lamp (La). In particular, if the discharge lamp (La) is operated at a dimmed light output level, the light output is sensitive to changes in the lamp voltage (VLa), possibly resulting in flickering. In order to control stable lamp operation and prevent flickering, a high-sp feedback circuit is provided for controlling an operating frequency. In order to provide a relatively large dimming range for controlling the light output level, a low-speed feedback circuit is provided for controlling a DC supply voltage level (VDC).

Abstract: An illumination system (10) comprises: —a light source (11); —a controller (12) controlling the power output of the light source; —a light sensor (16) wirelessly communicating with the controller. In a normal mode, the controller controls the light source such that the light level remains substantially constant. In a change mode, the controller controls the light source such that the light level is gradually changed with a predetermined change rate (R) such as to decrease a deviation from a target level (LT). The controller switches from its normalmode to its change mode on the basis of input signals received from the light sensor. The light sensor measures a light level, and decides whether or notto communicate a signalto the controller. The light sensor refrains from transmitting a signal when receiving the signal will not cause the controller to change its control behaviour.

Abstract: A collaboration program operates on a computer system for storing, sharing and synchronizing data between different users. Centrally stored content data items are organized by associations into one or more folders, with the folders arranged by associations in a multi-level hierarchical structure. Users have access to all folders and content data items falling within at least one top level folder or “file cabinet” viewable by that user. When a user makes a change/addition to the hierarchical structure, that change/addition is transmitted to a server, which makes the change/addition to the necessary associations and sends messages through a TCP/IP format advising other signed-on users of the change/addition.

Abstract: A lamp assembly for a controlled environment chamber comprises a frame, a plurality of fluorescent lamps supported on the frame and spaced apart from one another and a plurality of sleeves. Each sleeve is disposed about a respective fluorescent lamp at a distance therefrom to form a space between said sleeve and said respective fluorescent lamp, said sleeve being sealed about said respective fluorescent lamp to prevent air from outside said sleeve from reaching said respective fluorescent lamp. The sleeves are spaced apart to allow airflow therebetween. With the space between each sleeve and the respective lamp being fluidly isolated from air surrounding the sleeve, the light intensity output of the lamp is not as susceptible to reduction under temperature fluctuation in the chamber interior outside the sleeves, while said air remains free to flow between the lamps from one side of the lamp assembly to the other.

Abstract: Shelf support apparatus can be moved and stacked with a tined lift such as a forklift. The apparatus has based feet disposed lower than a front base cross member, and support uprights extend upward therefrom to a generally horizontal top structure. The front base cross member has two tine openings with lift tubes for receiving lift tines of a fork lift, and a bottom surface for receiving lift tines of a floor pallet jack. The top structure includes feet-receiving openings corresponding in location to the base feet, such that the apparatus can be stacked. The base feet have targeting slopes both in a front-to-back direction and in a side-to-side direction, to guide the second, upper shelf support apparatus down onto the first, lower shelf support apparatus with the base feet received in a nesting relationship. The targeting slopes in the front-to-back direction acts over a targeting area which is greater than the targeting area in the side-to-side direction.
