Abstract: A method and a controller are disclosed. The method in includes obtaining, by a controller of an elevator system, a sensor event associated with a location in a building; and changing, by the controller, the state of at least one elevator associated with the location from an idle state to an active state.

Abstract: A method for storing a water-soluble undissolved silica-based material, optionally with an incorporated functional agent. The method includes immersing the material in an aqueous liquid phase which is initially saturated with a water-soluble silica-based material which is the same or different than the undissolved silica-based material, such that the undissolved silica-based material does not essentially dissolve into the liquid phase during storage, or the proportion of the amount of the initially undissolved silica-based material to the amount of the liquid phase is such that the liquid phase will be saturated or essentially saturated by a dissolved portion of the water-soluble undissolved silica-based material during storage, which dissolved portion of said water soluble undissolved silica-based material is less than 20%. Also disclosed is a storage package which may preferably be used to store functional agents, delivery devices or implants.

Abstract: A method for producing a flowing silica composition including a sol-gel transfer, where redispersion is carried out. The redispersion includes adding, after having reached gel point of the sol-gel transfer, liquid into the gel formed by the sol-gel transfer, and the addition being made within a sufficiently short time period after reaching the gel point, to result, after mixing of the gel and the liquid, in a rheologically homogenous flowing silica composition, which is and remains injectable as such, or by short stirring <30 s, through a thin 22G needle. Also disclosed are flowing silica compositions and gels obtainable by methods of the invention, and uses of flowing silica compositions.

Abstract: A biodegradable carrier is produced for preservation and/or controlled delivery of biologically active agents where said biodegradable carrier is a silica xerogel which is made from water and silane by using acid or base as a catalyst, and biologically active agents in said biodegradable carrier are infecting and/or transfecting viruses. Silica xerogel material can be pharmaceutically acceptable and it can be used as a medicine.

Abstract: The invention is concerned with a method and system for modification of audio signals including pitch-bending of the audio signals in accordance with a control signal. The audio signal consists of an input signal defining the point at which the audio signal is received and of a control signal defining the desired change of the signal pitch. The method comprises digitizing and storing samples of the input signal in a data file memory in such a form that each piece of signal data is placed in a queue having an input pointer that locates the next available storage location and output pointer that locates the next location to read from the queue.
