A light-emitting diode (LED) emitter and a LED lamp having the same are revealed. The LED emitter includes a first LED chip string, a second LED chip string, a substrate, two electrodes, a high-color-temperature phosphor layer and a low-color-temperature phosphor layer. The substrate where the first LED chip string and the second LED chip string are arranged is electrically connected to the two electrodes. The high-color-temperature phosphor layer and low-color-temperature phosphor layer cover the first LED chip string and the second LED chip string respectively. The total resistance value of the first LED chip string is different from the total resistance value of the second LED chip string.

An LED filament bulb includes a driver and two filament sets. The driver includes a rectifier circuit, a filter circuit, a constant voltage (CV) circuit, a first constant current (CC) circuit and a second CC circuit. The rectifier circuit converts an AC power into a DC power. The filter circuit connects the rectifier circuit for filtering an AC component. The CV circuit connects the filter circuit for generating a fixed voltage and outputting the fixed voltage via a voltage output end. The voltage output end connects a first electrode of each filament set. The first CC circuit connects both the CV circuit and a second electrode of one of the filament sets. The second CC circuit connects both the CV circuit and a second electrode of another one of the filament sets. The CC circuits make currents flowing through the two filament sets identical.

A chair-like exercising apparatus comprises a back, a seat, front legs, rear legs, and resistance element(s) which provide a broad range of resistance force adjustable by the user for the back extension exercise. The chair back pivotally connects to the rear legs directly, and pivotally connects to the front legs or rear legs through the resistance element(s). The resistance element comprises a compress-coil-spring cylinders (or constant-force-spring devices) and the cylinder holders (or the device holders). The resistance level of the back extension exercise is adjusted by switching the interchangeable compress-coil-spring cylinders (or constant-force-spring devices) of appropriate loads inside the cylinder holders (or device holders). A user sits on the chair and sway backward to perform back extension exercise after selecting an appropriate resistance level based on his/her physical condition. The apparatus is simple, affordable and can be used as a regular chair in its locked position. A regular back extension exercise with proper resistance force strengthens the low back muscles (erector spinae), improves and prevents the low back pain symptoms.

An electric vehicle driving system includes an energy-storage apparatus (1), a first motor (2), a speed regulating motor (3) and a single row planetary mechanism. Said first motor (2) and said speed regulating motor (3) are connected electrically to the energy-storage apparatus (1). The single row planetary mechanism includes a sun gear (4), a gear ring (5) and a planetary carries (6) with planetary gears (7). The planetary gears (7) in the planetary carrier (6) mesh the gear ring (5) and the sun gear (4) separately. The output axle of the first motor (2) is connected to the gear ring (5), and the output axle of the speed regulating motor (3) is connected to the sun gear (4) by a brake (8). The invention takes the speed regulating motor and the single row planetary mechanism instead of the gearbox in a transmission driving system, and achieves a simple and compact structure, easy assemble, light weight, and low manufacturing cost. With the speed regulation of the speed regulating motor, the first motor works in high efficiency speed range, which increases energy utilization rate and endurance mileage.

A side lobe suppression method for an SAR image based on the deformation of a spatial spectral support area is provided. Using the relationship between the spatial spectral support area distribution of an SAR system and an impulse response, the trend of a side lobe in the impulse response is changed by deforming the spatial spectral support area; two SAR images with different side lobe trends are obtained by calculation; the difference information of the side lobe trends between the two SAR images is finally utilized to realize the mutual separation of a target main lobe and the side lobe, thus realizing effective side lobe suppression. The method has an obvious effect on side lobe suppression without losing image resolution, at the same time, can be realized simply, has less calculation amount, is not sensitive to noise, is also very convenient to implement, and can be directly used for processing an original SAR image.
