A method for the production of a sol-gel based matrix resulting in a sol-gel based matrix with high stability and high porosity. The sol-gel based material may be used for the production of a composite or sensor suitable for monitoring analytes.

A polysiloxane-substituted quinacridone pigment is produced by a quinacridone pigment with an epoxy-terminated polysiloxane under conditions effective to cause the epoxy group on the polysiloxane to react with, and bond the polysiloxane to, the quinacridone pigment. The quinacridone pigment thus produced has the polysiloxane grouping bonded to one of the quinacridone nitrogen atoms via a hydrocarbon linking group, which bears a hydroxyl group on a carbon atom α or β to the quinacridone nitrogen atom. These quinacridone pigments are useful in electrophoretic displays.

In formula (1), R.sub.1 to R.sub.24 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a silyl group, and a cyano group. ##STR00001##

An at least partly implantable system for injecting a substance into a patient's body. The system comprises at least one flexibly bendable infusion needle with a tip end of each of said at least one infusion needle arranged in at least one first housing for penetrating the first housing's outer wall in at least one penetration area and having the respective other end arranged in at least one second housing, the first and second housings being adapted for implantation inside the patient's body, wherein the at least one second housing is provided for implantation inside the patient's body remote from the at least one first housing and wherein the injection needle is sufficiently long to bridge the distance from the at least one second housing for remote implantation to the at least one first housing and further through the first housing up to the outer wall of the first housing. The system further comprises at least one drive unit adapted for being coupled to the at least one infusion needle and arranged at least for advancing the tip end of the at least one infusion needle so that the at least one infusion needle penetrates with the tip end or ends thereof said at least one first housing's outer wall in said at least one penetration area.

Methods, systems, and apparatus for monitoring and controlling electronic devices using wired and wireless protocols are disclosed. The systems and apparatus may monitor their environment for signals from electronic devices. The systems and apparatus may take and disambiguate the signals that are received from the devices in their environment to identify the devices and associate control signals with the devices. The systems and apparatus may use communication means to send control signals to the identified electronic devices. Multiple apparatuses or systems may be connected together into networks, including mesh networks, to make for a more robust architecture.
