The invention discloses a method for retrieving a point of interest and a terminal thereof, relates to the field of location-based services, and aims to solve the problem that the point of interest is not determined by a plurality of locations existing in the prior art. The method comprises the following the steps of: acquiring a collection of potential points of interest; and finding the target point of interest from the collection of potential points of interest, wherein the location relationships between the target point of interest and at least two known locations meet the preset rule 1. The method may also comprises the following steps of: finding a target location point, wherein the location relationships between the target location point and at least two known locations meet the preset rule; and searching the target point of interest in a preset distance range of the target location point. The method and the terminal are mainly applied in the field of location-based services.

The invention discloses a multi-temperature-region ice-temperature fresh keeping storehouse and a fresh keeping method for bergamot pears. The multi-temperature-region ice-temperature fresh keeping storehouse for the bergamot pears comprises a precooling region, a feeding and discharging channel, a cooling region, an ice temperature detecting device, a grading device, a conveyer belt control device, an automatic storing device, and a temperature rise and fall buffering channel, wherein the cooling region comprises four freezers, and the four freezers are respectively a first freezer of which the storing temperature is 0 DEG C, a second freezer of which the storing temperature is minus 1 DEG C, a third freezer of which the storing temperature is minus 2 DEG C, and a fourth freezer of which the storing temperature is minus 3 DEG C; and the four freezers are connected level by level according to a temperature lapse rule. According to the multi-temperature-region ice-temperature fresh keeping storehouse disclosed by the invention, multi-temperature-region graded storage of the bergamot pears is realized according to the value of ice temperature. Compared with conventional static ice temperature storage, the multi-temperature-region ice-temperature fresh keeping storehouse and the fresh keeping method for the bergamot pears disclosed by the invention have the advantages that the storing partitions of the bergamot pears can be dynamically adjusted according to the changes of the ice point temperature of the bergamot pears, so that the situation that the bergamot pears are always stored under the condition of being close to the ice point temperature can be guaranteed, the bergamot pear fruits are prevented from freeze injury, and the shelf life of the bergamot pears is prolonged.

The invention relates to a sensor arrangement (1) for the contactless sensing of angles of rotation on a rotating part, said rotating part being coupled to a disk-shaped target (20) which includes at least one metal area (24) and generates, in combination with a coil arrangement (40) comprising at least one flat detection coil (42, 44, 46), at least one piece of information to determine the current angle of rotation of the rotating part. According to the invention, at least one measurement circuit (3) converts the inductance of a corresponding flat detection coil (42, 44, 46) into a measurement signal (UM) which an evaluation and control unit (10) acquires using measurement technology and evaluates in order to calculate the angle of rotation, the inductance of the detection coil (42, 44, 46) changing under the effect of eddy currents in accordance with the degree of overlap between the detection coil and the at least one metal area (24) of the rotating target (20).
