Battery charger

The present invention provides a battery charger capable of charging a plurality of secondary batteries which are used in different types of apparatuses, such as an electric vehicle and a mobile power supply unit, in a simultaneous or concurrent manner without largely occupying an installation space on the ground. A DC power supply section 22 includes a plurality of DC stabilized power supply circuits each operable to supply an output according to required electric power, therefrom in an independent manner. Specifically, based on information from each of a plurality of secondary batteries, and information set up/input through a setup/input section, one of or a combination of two or more of the DC stabilized power supply circuits is selected for each of the secondary batteries. Then, an electric power supply line between the selected one of or the selected combination of two or more of the DC stabilized power supply circuits and each of the secondary batteries to be charged is configured, and an output of the selected one of or the selected combination of two or more of the DC stabilized power supply circuits is adjusted. This makes it possible to configure respective electric power supply lines for the secondary batteries to allow the secondary batteries to be concurrently charged, and adjust respective electric power amounts to be supplied to the secondary batteries, individually.

Method for reading radiation image from stimulable phosphor sheet

A method for reading a radiation image from a stimulable phosphor sheet composed of a substrate and a stimulable phosphor layer containing a latent radiation image by as of a radiation image-reading means having a stimulating light-applying unit and a stimulated emission-collecting unit having a lens and a stimulated emission-receiving plane, which is performed by the steps of applying a stimulating light onto the phosphor layer under the condition that the phosphor sheet moves along its sheet plane in relation to the stimulated emission-collecting unit; collecting a stimulated emission emitting from the area onto which the stimulating light is applied on the emission-receiving plane through the lens; and photoelectrically converting the collected emission into electric signals in the stimulated emission-collecting unit, is improved by moving the stimulable phosphor sheet in relation to the emission-collecting unit under the condition that the stimulating light-applied area of the stimulable phosphor layer is kept apart from the center of the emission-receiving plane with a space in the range defined by a combination of a reference space and a focal depth of the lens, in which the reference space is defined by a length at which the stimulated emission emitting from the phosphor layer focuses on the emission-receiving plane after passing through the lens.

Electrolyte for lithium ion battery and preparation method thereof

The invention discloses an electrolyte for a lithium ion battery and a preparation method thereof. The electrolyte consists of a main electrolyte, an electrolyte additive, a main solvent and a solvent additive. The preparation method comprises the following steps of: A. under the condition of vacuum or inert gas protection, respectively mixing the main solvent and the solvent additive with a drying agent (lithium oxide) which is dried to be at constant weight in advance, and mixing and filtering to remove the lithium oxide and lithium hydroxide sediment; B. uniformly mixing the dried main solvent and the dried solvent additive from the step A; and C. adding a main electrolyte mixture and an electrolyte additive into the solvent mixed in the step B, and agitating and dissolving under the vacuum and inert gas protection to prepare a solution with the mass mol concentration of the main electrolyte of 0.5-1.5 M. The electrolyte has the advantages of abundant resources, low price and no toxin, effectively improves the work temperature range of the battery and effectively prolongs the circulating service life of the battery, so that various types of the lithium ion batteries are manufactured; and the electrolyte is particularly suitable for manufacturing a lithium ion power battery with high power capacity and high multiplying power charging and discharging capacity.

Indoor fingerprint positioning method and system based on geomagnetic sensor array

The invention relates to an indoor fingerprint positioning method and system based on a geomagnetic sensor array. The positioning method comprises the following steps: 1, performing grid initialization; 2, collecting fingerprint data at sampling points in a grid through the geomagnetic sensor array; 3, storing fingerprint at save positions in a fingerprint database to complete the construction ofa geomagnetic reference map; 4, acquiring the geomagnetic information of a to-be-detected point by using the geomagnetic array, and sequentially calculating fingerprint similarity between the to-be-detected point and the probability characterization fingerprint of each sampling position in the fingerprint database; and 5, selecting optimal-matching fingerprint from the geomagnetic reference map soas to obtain an estimated position. Compared with the prior art, the indoor positioning method based on the mobile crowdsourcing of the invention does not require manual surveying, realizes real-time, robust and accurate indoor positioning in virtue of a large number of ordinary users, greatly improves the working efficiency and stability of the system, and is beneficial for promoting the effective application of an indoor positioning technology.
