Patent CA-2112460-A1 (CA)
Inventor: ARWEILER HANS-WERNER
IPC: H04L12/26
Filed: 1992-05-12
Abstract: ABSTRACT   Test data are inserted on the data source side into a data stream (DS) transmitted to a data receiver (5) from a data source (1) via at least one transmission section (4). A bit error function (e(n)) is obtained from the test data received. The bit error function (e(n)) is evaluated in a part by part manner to discover its periodicity, the length of the partial section evaluated at the same time being measured in such a way that it contains a plurality of bit errors (BF). The bit error function (e(n) or err(n)) is subjected to auto-correlation. The maxima (M,M1, ...Mi) of the auto-correlation functions (AKF(m)) thus obtained are used to determine the nature of the interference (10, 11) with reference to its stochastic or deterministic nature.

Title: Composting toilet
Inventor: SUNDBERG HENRIC
IPC: C05F17/90
Filed: 1994-03-24
Abstract: A composting toilet comprising a housing having a seat disposed about an opening communicating with an aeration drum for receiving human waste matter. The drum is rotatably-mounted for rotation about a longitudinal axis oriented horizontally inside the housing which has air inlet and air outlet means for venting the toilet. A removable receptacle adapted to receive decomposed solid waste matter from the aeration drum for periodic removal from the toilet is also provided. The aeration drum has a narrow front end with waste access means for receiving and discharging waste therefrom, and a wide rear end extending radially outwardly from the front end. The rear end has liquid discharge means in fluid communication with the housing and a gas outlet means is disposed opposite the liquid discharge means to cause an airflow through the composting solid waste and for venting any gases which enter the aeration drum or are formed through decomposition inside the drum. The configuration of the drum with the wide rear end is designed to collect said gases in the rear end away from the seat area, provides increased capacity at the rear of the toilet so as to allow the seat which is at the front of the toilet to be lower and more conveniently accessible by a user, and defines a rear bottom surface which is always lower than at the front of the drum thereby improving the separation of liquid waste from solid waste.

Title: Double nail guiding system for targeting of distal screw holes of interlocking nails
Inventor: HWANG CHI-YUAN
IPC: A61B17/17
Filed: 1994-04-21
Abstract: A double nail guiding system for stabilizing broken bones includes a twin jig, first and second interlocking nails extending from the twin jig, wherein each interlocking nail defines a channel along a longitudinal axis thereof.  The interlocking nails also include a distal portion which includes at least one hole.  A centric or eccentric guiding pipe, including a channel in the center, extends through the first interlocking nail in a direction toward the second interlocking nail.  A K-wire is inserted into the channel in the guiding pipe, such that the K-wire extends through the guiding pipe and through the hole defined in the second interlocking nail which is in the bone being stabilized.  A guide probe is inserted into the channel in the second interlocking nail (which is in the bone) toward the distal portion thereof.  In this manner, alignment of the hole in the distal portion of the first interlocking nail and the hole in the distal portion of the second interlocking nail is confirmed by contacting the guide probe with the K-wire.          Advantageously, the first interlocking nail and the second interlocking nail are constructed to be of equal length and equal size. The procedures of distal locking screw targeting were simplified with an 100% successful rate. The radiation exposure to the patient and the surgeon's hand is no longer necessary during the distal locking of femur.

IPC: H04L12/58
Filed: 1995-01-23
Abstract: A network agent system in which the functions of the agent are partitioned between a task agent and a user agent for each user of the the agent system. The task agent and the user agents communicate by means of a protocol which is implemented in electronic mail messages. The messages of the protocol are intensional rather than extensional, and the response of a user agent to a message is determined by the user's hardware environment and preferences. The partition of the functions and the use of electronic mail as the communications medium provide important advantagesin the areas of security, privacy, and adaptability. The disclosed network agent is a schedlller for visitors. Features of the scheduler include a user interface which offers more than a yes-no choice and the translation of the scheduling problem into a general integer programming problem.
