Abstract

A driver arrangement for powering a first load in an operation mode and a second load in a second mode. In the operation mode, a power factor correction circuitry generates a PFC output signal that powers the first load, and a switched-mode power supply is able to generate an offset signal that is superimposed over the PFC output signal for attenuating a ripple in the PFC output signal. In the second mode, the power factor correction circuitry is disabled and the switched-mode power supply is able to generate a supply power for the second load meanwhile disabled from generating the offset signal. The switched-mode power supply therefore provides a dual functionality.

Abstract

Proposed is a driver circuit for a lighting device which caters for both a control method using an electronic control signal and a manual control signal. The driver circuit has a power control circuit and a selection circuit. The selection circuit is configured to control the power control circuit so that a manual control signal is either employed or disregarded. In this way, the power control circuit may be controlled to set the output power of the driver circuit according to either the manual control signal or an electronic control signal. Specifically, the electronic control signal is prioritized over the manual control signal when the electronic control signal is valid.

Abstract

This invention relates to a wireless mesh network for high-capacity backhauling of data traffic such as for telecommunications networks. Reliability is increased through resilience, i.e., data traffic can be transported via multiple paths between customer equipment (e.g., telecommunication cells) and fiber points. Depending on a network status, a node can choose to direct traffic via a different path, thus reducing the chance of packet drops. Once resilience is established, network traffic can be optimized to respond to variable natures of traffic density. By doing this, network reliability can be further increased and throughput optimized while minimizing costs.

Abstract

A method of determining a detection area of a ToF sensor mounted on a ceiling of a room, is presented. The ToF sensor is included in a first device, such as a ceiling panel or luminaire, having predefined dimensions. The method includes obtaining the predefined dimensions of the first device in a second device, which is a user's device such as a smartphone or tablet; obtaining a first image of the room including the first device from a camera of the second device; obtaining a second image of the room including a desired detection area from the camera; determining a projection of the ToF sensor on the second image based on the predefined dimensions of the first device; and determining, using the ToF sensor, a height of a reference object such as a toilet (616) on a floor (716) of the room. The ToF sensor may be repositioned for obtaining an improved detection area. To get the projection (700) of the ToF sensor on the floor (716), the processor of the smartphone may construct two lines (740, 742) on the floor in the camera view which is to visualize the detection area as a dashed box (ABCD) overlayed on the second image, e.g., by using an augmented reality mode of the camera. The camera view (730) includes also a front wall (634) and a side wall (636) of the room. The ToF sensor may be used for fall detection, most advantageously for the detection of elderly people falling.

Abstract

The invention is directed to a lighting-and-communication arrangement (100), comprising a plurality of lighting-and-communication devices (102, 102a, 102b) and an arrangement control unit (150), wherein each lighting-and-communication device comprises a lighting device (104) identifiable by lighting-device data (LID) and a communication device (106) identifiable by radio-identification data (RID).The lighting device comprises a lighting control unit (110) comprising a location ascertainment unit (114) configured to ascertain location data (LD) indicative of a current installation location of the lighting-and-communication device. The arrangement control unit is configured to generate, using the lighting-device identification data (LID), the radio-identification data (RID) and the location data (LD), a network planning database (160) indicative of pairs of communication devices suitable for establishing a radio-communication link between them, according to a selection algorithm (156). Using the network planning database commissioning data (124) is generated and provided for establishing the radio-communication links between the pairs of communication devices.
