Title: Detection strip for detecting and identifying chemical air contaminants, and portable detection kit comprising said strips
Inventor: KLEINGELD ADRIAAN
IPC: G01N31/22
Filed: 1990-02-21
Abstract: ABSTRACT:     The invention relates to a detection strip for detecting and identifying chemical air contaminants, comprising a holder having a plurality of spaced carriers which are capable of absorbing the air contaminants and which optionally comprise reagents which can be influenced by the air contaminants, and having a plurality of colour-producing agents oppositely to the carriers, which agents, in contact with the absorbed air contaminants or with the reagents, depending on whether or not these reagents have been influenced, can cause a colour reaction in the presence of a liquid, in which the colour-producing agents, dissolved in the quantities of liquid required for the colour reaction, are accommodated in closed reservoirs having an easily breakable wall; and in which the collecti-ve reservoires are provided between the carriers and a strip of a slightly flexible material (flexible strip) in such a manner that when a mechanical pressure is exerted on said flexible strip at the area of the reservoirs said flexible strip will yield, as a result of which the reservoirs, in case the carriers are supported, will break and the contents thereof will be contacted with the absorbed air contaminants or with the reagents. The invention also relates to a portable detection kit which, in addition to a number of these detection strips, comprises at least one device for breaking the reservoirs accommodated in the detection strips.

IPC: A61N1/30
Filed: 1990-04-27
Abstract: A selectively permeable membrane (14) is positioned between the agent reservoir (15) and the electrode (11) of a donor electrode assembly (8) in an iontophoretic delivery device (10). Optionally, an electrolyte reservoir (13) is positioned intermediate the electrode (11) and the agent reservoir (15). In certain embodiments, the membrane (14) is permeable to species of less than a predetermined molecular weight and substantially less permeable to species of greater than the predetermined molecular weight.

Patent CA-2023872-A1 (CA)
IPC: G06F21/20
Filed: 1990-08-23
Abstract: An improved security system, including a portable smart card and a host computer, eliminates the need for the computer to store individual personal identification (ID) numbers for each user seeking access to the computer. Instead, the computer stores a first encryption algorithm E1 used in converting a particular identification number (ID)n into a secret code Sn for that particular user. Sn also exists within the memory of the smart card having been loaded into its memory atthe time of issue. A challenge number C is generated by the computer and transmitted to the smart card. Within the smart card and the computer, microprocessors respond to the challenge number C, the secret code Sn, and a second encryption algorithm E2 in order to generate response numbers Rn and R'n respectively. Thereafter, Rn is transmitted to the computer where it is comparedwith R'n.  A favorable comparison is necessary for gaining access to the computer.

Abstract: In a speech parameter encoding method of encoding an input speech signal into a sequence of encoded signals, vector quantization is carried out through a plurality of vector quantizers which are connected in cascade to one another through subtractors and which cooperate with code books, respectively. Such a cascade connection of the vector quantizers may be supplied with the input speech signal either at every frame or at every subframe shorter than the frame to produce a set of code vector candidates from each of the vector quantizers.          Each set of the code vector candidates is sent to a cumulative distortion calculator to select an optimum combination of the code vector candidates and to produce, as the encoded signals, an index representative of the optimum combination.  Alternatively, a sequence of coefficients which represent a spectrum parameter is calculated at every frame and is divided into a plurality of coefficient groups each of which is subjected to vector quantization to produce a plurality of code vector candidates for each coefficient group.  Cumulative distortions are calculated for combinations of the code vector candidates to select an optimum combination.
