Abstract: A call control method includes: establishing a Bluetooth connection with a mobile terminal; obtaining call information of the mobile terminal; determining whether a number corresponding to a call event is an empty number or a number of the mobile terminal, the call event being an event corresponding to the call information; in response to the number corresponding to the call event being neither an empty number nor the number of the mobile terminal, determining that the call event is a phone call event, and in response to the number corresponding to the call event being either an empty number or the number of the mobile terminal, determining that the call event is not a phone call event; and loading a call interface only when it is determined that the call event is a phone call event.

Abstract: An intelligent defrosting control for an air conditioner is disclosed, which comprises the following steps: setting a standard air pressure value; placing a high-pressure sensor on the exhaust pipe of the compressor of the air conditioner to measure the air pressure; When the air pressure measured by the high-pressure sensor is lower than the standard air pressure value, said air conditioner begins to come into the defrosting mode; otherwise, said air conditioner working in previous mode.

Abstract: The present invention relates to polymorphs of the 3-pyrrole substituted 2-indolinone compound 5-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-pyrrolidin-1-yl-ethyl)-amide.

Abstract: A method for deriving true density of a powder for compaction to prepare a pharmaceutical tablet comprises (a) preparing by compaction of the powder a plurality of tablets at different compaction pressures defining a range from low to high compaction pressures; (b) determining tablet density of tablets prepared at each compaction pressure to obtain compaction pressure versus tablet density data; and (c) fitting the data to a modified Heckel equation by a nonlinear regression procedure to yield a value for true density of the powder. The method can be applied to water-containing as well as substantially water-free powders and is useful in situations where helium pycnometry is unavailable or inapplicable.
