Patent CA-2550351-A1 (CA)
Title: Multiphase active ingredient formulation
Inventor: HOFMANN STEFAN
IPC: A01N51/00
Filed: 2004-12-15
Abstract: The invention relates to a formulation having a plurality of phases containing active ingredients. Said formulation is characterised in that: it contains a first, innermost, finely distributed phase (I) consisting of active ingredients or an active ingredient solution, preferably some of the phase particles being surrounded by a barrier sheath (M); the formulation has a second, intermediate phase (II) that serves as a dispersant for the first, inner phase (I) and can also be dissolved in the active ingredient; and the formulation has a third, outer phase (III) that serves as a dispersant for the second intermediate phase and can, in turn, be dissolved in the active ingredient and/or can be in the form of solid particles that can, in turn, be surrounded by a barrier sheath. In this way, a plurality of biological active ingredients can be produced in the different phases in different concentrations and with a respectively controlled release rate in a single formulation. According to the invention, a mechanical stabilisation is achieved by solidifying the intermediate phase (II), enabling the formulation to be stable for a longer period of time even once it has been applied to a surface. Furthermore, by selecting a suitable solvent for the outer phase, the formulations limit the release of the active ingredient from the innermost phase, and the capsules are not emptied and can thus be stored for a longer period of time.

Title: Adaptive advertisements
Inventor: FRASER DANIEL JOSEPH
IPC: G06Q30/02
Filed: 2006-07-10
Abstract: An advertising system for displaying adaptive advertisements that can change the displayed content in response to external inputs can be used in public places such as transit stations, arenas, stadiums, retail stores, and squares. The advertising system can also be deployed in transit vehicles. The advertisements make use of a decision engine to select from a plurality of advertising scenarios to generate the content that is rendered on displays. The system has a processor that executes the decision engine and provides the decision engine with the external inputs, such as time of day, weather conditions and forecast, current, past or next transit station, required to select one of the stored advertising scenarios. These input scenarios can be either stored by the system or obtained in real-time.

Patent CA-2601731-A1 (CA)
Title: Methods and apparatuses for operating groups of high-power leds
Inventor: CREMER ANTONIUS JACOBUS MARIA
IPC: H05B44/00
Filed: 2006-04-07
Abstract: The object of the invention is to implement an energy-efficient, compact and cost-effective solution for driving a number of high- power LED groups for lighting applications, by using a single switching power supply together with LEDs connected in series and/or in parallel and pulse width-controlled switches in parallel across the individually controllable LED groups. If the switch of an LED group is ON, the LED group will not light up. If the switch is in the OFF position, the full current of the power supply will pass through the corresponding LED group. Another aspect of the invention is the restriction within the drive protocol, according to which but a single switch is actuated at any one time within a particular time interval. This aspect guarantees a minimum time interval between each individual actuation event.  Another aspect is the derating of the power supply in those phases where not a single LED group is ON. In the event of all the switches being closed (all LED  groups OFF) the power supply can be derated (or turned off). A further aspect is the use of an elevated current setting of the power supply with the simultaneous restriction of the ON cycle by means of pulse width modulation.  The power supply is set to the maximum instantaneous peak current of the LED, while maximum pulse width drive guarantees a maximum of the average LED  current, cycle time being left over as a result, thus enabling more LEDs to be driven at a given supply voltage.
