Abstract: The method permits the detection of ‘standby’ state’ in linear and non-linear loads connected to the power grid and their automatic disconnection, and comprises at least the detection of the normal operating state of at least one load by means of detection, and obtaining the maximum value of the current in said operating state for the determination of the ‘standby state’ of the at least one load.

Abstract: A method is provided that permits the detection of ‘standby’ state’ in linear and non-linear loads connected to the power grid and their automatic disconnection. The method includes five main stages: a) detecting the normal operating state of at least one load by a detection device, b) obtaining the maximum value of the current in the operating state, c) detecting entry into ‘standby’ mode’ by the load by establishing the ‘standby’ state’ when the current value measured at a specific time in each load is less than a percentage P of the maximum value of the current of each load in normal operating state, d) evaluating the value for each load for a predetermined time T, and e) disconnecting the load and the detection device when value T of time is reached without the load having returned to the normal operating state. A system is also provided.

Abstract: A portable safety, entertainment and communication device for a bicycle is provided. The device brings together a plurality of functions in a single device that can be fixed to the handlebar of a bicycle. The device is configured to automatically detect whether a casing is connected to a support and change the functionality of various elements of the device if so. In one aspect, the device changes the functionality of a digital music player so that a user may listen to music through speakers when the casing is connected to the support and listen to music through headphones connected to an audio output port when the casing is not connected to the support. Various other modules providing functionality may also be included in the device, such as a video camera and/or digital camera and a light source.

Abstract: The method permits the detection of ‘standby’ state’ in linear and non-linear loads connected to the power grid and their automatic disconnection, and comprises 4 main stages: a) Detection of the normal operating state of at least one load by means of detection, obtaining the maximum value of the current in said operating state, b) Detection of entry into ‘standby’ mode’ of the at least one load by the means of detection establishing said ‘standby’ state’ when the existing current value obtained in each load is less than a percentage P of the maximum value of the current of each load in normal operating state, c) Start of means of timing at a determined time T for each load when it goes into ‘standby’ mode’, and d) Disconnection of the at least one load and of the means of detection when value T is reached of the means of timing without the at least one load having returned to normal operating state.
