Title: Method and apparatus for improving the quality of speech signals transmitted over wireless communication facilities
Inventor: MEYERS MARTIN HOWARD
IPC: H04W52/18
Filed: 1999-07-29
Abstract: It has been recognized that in a wireless communication system certain frames of encoded speech data transmitted between a base station and a mobile unit, or between a mobile unit and a base station, are more critical than others. A frame may be determined to be erased by the receiving base station or mobile unit due to noise or interference over the wireless transmission medium. If an erased frame cannot be recreated from one or more preceding frames, then it is more critical than a frame that can be recreated by an extrapolation of data from one or more preceding frames. Accordingly, on a frame-by-frame basis, each frame in a sequence of frames is identified as being critical or non-critical.  Each frame that is identified as being critical is then transmitted in a manner that is more robust than the manner in which non-critical frames are transmitted to decrease the likelihood that a receiver will determine that the frame is erased. In a CDMA system, a current frame is identified as being critical by forming a weighted sum of the differences between corresponding frame parameters that represent the current frame and frame parameters that represent a previous frame. That weighted sum is compared with a threshold. If the weighted sum exceeds the threshold, then the current frame is classified as being a critical frame and is transmitted at a higher output level than non-critical frames are transmitted.

Abstract: The invention concerns an assembly comprising a rim (12) and a closed toric tyre (1), the latter including a tyre tread (11) and a hoop, defining a sealed chamber (10). The hoop (13) constitutes a rim (12) mounting base, and forms a sleeve designed to be supported on said rim in mounting position. The hoop (13) comprises a protuberance (140) with a lateral blocking fit (14) designed to be engaged in a matching groove (120) arranged on the rim (12) to counter axially any relative movement between the tyre and the rim at least in one direction. The hoop has a certain degree of flexibility such that when pressure is removed from the chamber (10) said protuberance is displaced towards the larger radii. For instance the tyre (1) can be mounted on the rim (12), and the vacuum cancelled such that the protuberance (140) becomes engaged in the groove (120).

Title: Apparatus for making filter cigarettes
Inventor: OZERAY PHILEFFE
IPC: A24C5/47
Filed: 1999-10-06
Abstract: Groups of coaxial plain cigarettes and filter mouthpieces, particularly cigarettes and mouthpieces having elliptical cross-sectional outlines, carry ad-hesive-coated uniting bands at the time of entry into a channel between the peripheral rolling surface of a rotary drum and the complementary rolling surface of a stationary rolling member. The uniting bands are convoluted around portions of or the entire mouthpieces and around the neighboring portions of the respective cigarette or cigarettes. The inlet of the channel is defined or preceded by a transversely extending stationary group-contacting device having a raised first portion which cooperates with the drum to set the mouthpieces and the cigarettes of successive oncoming groups into simultaneous rolling motion, and such first portion is followed by a second portion having a concave guide surface which ensures predictable entry of successive groups into the rolling channel downstream of the first portion. The one and/or the other rolling surface and/or the guide surface is or can be grooved to ensure a more predictable rolling of groups in the channel.

Abstract: An ink cartridge of the present invention has a storage element, in which plural pieces of specific information relating to an ink cartridge are stored at specific addresses that respectively occupy minimum bits required for storage. Namely the storage capacities required for storing the respective pieces of specific information are different from one another. For example, a piece of information on the year of manufacture is registered in a data length of 7 bits, a piece of information on the month of manufacture is registered in a data length of 4 bits, and a piece of information on the date of manufacture is registered in a data length of 5 bits. A piece of information on the time (hour) of manufacture is registered in a data length of 5 bits, and a piece of information on the time (minute) of manufacture is registered in a data length of 6 bits. A piece of information on the validity term of ink is registered in a data length of 6 bits, and a piece of information on the after-unsealed validity term is registered in a data length of 5 bits. This arrangement enables the specific information relating to the ink cartridge, for example, pieces of information on the manufacture of the ink cartridge and those on remaining quantities of the respective inks,to be stored efficiently into the storage element,while reducing the manufacturing cost of the ink cartridge.
