A sheet stackable device includes a sheet stackable plane. The sheet stackable device includes a first tray and a second tray, each of which is formed in a shape of a flat plate. The first tray includes a first contact part. The second tray is slidable along a slidable direction between a first position, in which the second tray overlaps the first tray, and a second position, in which the second tray is dawn out of the first tray. The second tray includes a second contact part, which is slidable on the first contact part. At least one of the first contact part and the second contact part includes a rack with rack teeth, which are aligned along the slidable direction. An upper plane of the first tray and an upper plane of the second tray in the second position form at least a part of the stackable plane.

A system to control solid state light sources, including a photosensor responsive primarily to wavelengths of light outside the emitted light band of wavelengths that the solid state light sources emit when the solid state light sources are in the ON state, and which produces a light level signal representative of a level of sensed light primarily for wavelengths outside of the emitted light band of wavelengths. A set of circuitry receives the light level signal representative of the sensed level of light from the photosensor, determines a contribution by the solid state light sources to the sensed level of light, and uses a compensated light level or a compensated threshold in assessing a dusk condition or a dawn condition when the solid state light sources are in the ON state to compensate for the contribution by the solid state light sources to the sensed level of light.

The invention discloses a preparation technology of Al-Er alloy lead wire, comprising the following steps of: 1) configuring alloy, adding Er element into molten aluminium liquid (more than 99.9%) in a way of intermediate alloy according to the weight percentage of Er within the range of 0.07wt%-0.27wt%; 2) casting the aluminium liquid into cast ingots and then hot extruding into round aluminium rods; 3) carrying out solution treatment on the rods for 10h at the temperature of 640 DEG C, and then water quenching at the room temperature; and 4) carrying out heat preservation on the rods treated by quenching for 4-10h before being dawn and after being dawn at the temperature of 275-300 DEG C. The prepared lead wire maintains higher strength, good elongation percentage and good electric conduction performance.

Applicant has disclosed a method for controlling on and off times for streetlights by synchronizing these intervals to recent local daylight conditions without any human intervention. The preferred method comprises: sensing, via a photocell, when dusk and dawn occurs; and then, timing or counting the dusk and dawn times per 24-hour cycle, recording that dusk and dawn data, calculating the average dusk-to-dawn interval for a plurality of preceding 24-hour cycles; predicting, the next dusk time; and turning on the streetlight for a preselected percentage of the calculated average dusk-to-dawn interval. Future “on” time periods are repeatedly calculated as a percentage of the dark periods determined on one or several immediately prior nights, and so varies with the seasons. Unlike the prior art, Applicant's streetlight control does not require field programming or field inputs from the installer or time knowledge. It also does not require any external or internal precision clock or calendar.

The invention discloses an on-orbit management method suitable for a sun-synchronous morning and evening orbit satellite lithium-ion storage battery pack. The on-orbit management of the lithium-ion storage battery pack is determined according to the orbit calculation independently completed by the on-board computer, satellite three-axis attitude measurement, and sun azimuth judgment. mode, the on-orbit management mode includes the long-light period management mode, the earth shadow period management mode and the emergency state management mode, corresponding to the lithium-ion battery pack management strategies in the three on-orbit states of sun-synchronous morning and evening orbit satellites. The system of the invention solves the on-orbit self-management problem of the lithium-ion battery under complex working conditions such as long-term shelving of the lithium-ion battery pack during the long-light period of the sun-synchronous morning and evening orbit satellite, frequent charging and discharging of the battery pack during the shadow period, and deep discharge and rapid charging in an emergency state. Thus, the long-life, independent and reliable on-orbit operation of the sun-synchronous morning and evening orbit satellite power supply system is ensured.

A method includes projecting a dark virtual sky in a digital space. The dark virtual sky is transitioned to a dawn virtual sky in the digital space. The dawn virtual sky is altered to introduce a daytime virtual sky in the digital space. The daytime virtual sky is modified to produce a dusk virtual sky in the digital space. These operations are performed via color palette transitions in the virtual sky in the digital space in a time period of less than six minutes. The color palette transitions are in proportional time segments of a twenty-four hour day punctuated by periods of light and darkness of variable length corresponding to the revolution of the earth around the sun. A collection of gaze points is formed in the digital space. Each gaze point in the collection experiences cyclic changes between a minimum position and a maximum position during a gaze point size change cycle. Initially, each gaze point in the collection experiences different changes between the minimum position and the maximum position during initial gaze point size change cycles thereby forming a gaze point out-of-phase period. Subsequently, selected gaze points in the collection experience common changes between the minimum position and the maximum position during intermediate gaze point size change cycles thereby forming a gaze point hybrid phase period. Finally, all gaze points in the collection share common changes between the minimum position and the maximum position during final gaze point size change cycles thereby forming a gaze point in-phase period that lasts at least one half the time period of less than six minutes.

In a case where IR data of a near-infrared light image is data in which a visible light component and a near-infrared light component coexist, a point image restoration process is performed on the IR data using a first point image restoration filter based on a first point spread function for visible light of the optical system and a second point image restoration filter based on a second point spread function for near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data that is captured in a time zone of twilight or dawn by performing weighted averaging on a point image restoration process using the first point image restoration filter and a point image restoration process using the second point image restoration filter using a first gain α and a second gain β according to a light amount ratio between visible light and near-infrared light at the time of capturing the IR data.
