摘要： A compact bass speaker cabinet uses a long, narrow, tapered waveguide that acts as does a small radial portion of the air outside a large pulsating sphere, and has the same bass response as the large pulsating sphere. The smaller end is closed and the longer end is open. In one embodiment the inside of the waveguide is a rectangle about an inch thick and substantially as wide as the speaker or speakers that are mounted on the wider surface close to or slightly overlapping the closed end; and the inside surfaces are tapered so that they meet at a point which lies beyond the closed end by a distance equal to the radian wavelength of the longest sound wave that is to be produced.

摘要： Technologies are generally described herein for a mirror array display system. In some examples, a controller can be configured to execute various methods for displaying content using a mirror array display having a mirror array including a number of mirrors and a light source. The controller can obtain content for display. The controller can also determine at least one aiming parameter associated with the number of mirrors and the light source. The controller can also emit light using the light source and aim the light emitted by the light source to a convergence point to generate a three-dimensional representation of the content, wherein the light is aimed in accordance with the at least one aiming parameter.

摘要： Tags that are associated with an item such as a person or vehicle are caused to optically flicker out an identifying pattern when triggered by a user or a device at an access point (gate, computer, card reader, or the like). The association of the tag and item can include a physical attachment. The flickering light is analyzed and access is permitted if the data key encoded in the flickers is an authorizing code. A lamp such as a laser or LED is used to create the flickers.

摘要： Items, for example grocery items in a shopping cart or warehoused items being inventoried, are counted by electronically registering flickers from tags attached to, or incorporated into, the items. The registration takes place during an interval of time equal to the flicker repetition rate of the tags. For example, each item's tag might flicker out an identifying signal (preferably from an LED in the tag) in about a thousandth of a second, and repeat this flicker once a second. A detector registers all of the flickers from all of the items during a one-second interval, and thereby counts the items because each will have flickered once during that time. Other items, with different identifying flickers, can be counted during the same interval. Thus, large numbers of various tagged items can be counted rapidly.
摘要翻译： 物品，例如购物车中的杂货物品或被存货的仓储物品，通过电子地注册来自附于或并入物品的标签的闪烁来计数。 注册在与标签的闪烁重复率相等的时间间隔内进行。 例如，每个项目的标签可以在大约千分之一秒内闪烁识别信号（优选地从标签中的LED），并且每秒重复一次闪烁。 检测器在一秒钟的时间内记录所有项目的所有闪烁，从而对项目进行计数，因为在此期间每个闪烁都将闪烁一次。 其他项目，具有不同的识别闪烁，可以在同一时间间隔内进行计数。 因此，可以快速计数大量各种标记的物品。

摘要： Techniques for reinforcing concrete using rebar are disclosed. Some example embodiments may include prestressed concrete structures reinforced by twisted, threaded reinforcing bars. An example reinforcing bar for a prestressed concrete structure may include an elongated, generally cylindrical rod; an external thread disposed on the generally cylindrical rod, the external thread formed from an elongated, generally nonlinear channel wrapped about a radial surface of the generally cylindrical rod in a generally helical fashion. A base portion of the nonlinear channel may be disposed substantially against the radial surface of the generally cylindrical rod and/or an upstanding portion of the nonlinear channel may extend generally orthogonally from the radial surface of the generally cylindrical rod.

摘要： A digital license sharing method, system and apparatus is provided for use in a digital rights management system. Usage rights in respect of digital content are transferred between content player devices or applications by associating with each player a status indication. Transfer is carried out by transmitting a request to obtain the usage rights from a player requiring usage rights to a player currently holding the rights. The transferring player sets a first status indication to indicate that it is no longer entitled to exercise the rights, and transmits a response to the requesting player to transfer the usage rights. The requesting player then sets a second status indication to indicate that it is henceforth entitled to exercise the rights. Methods and apparatus for creating transferable licenses are also provided that employ a sharable license format including a validated portion and an unvalidated portion. The validated portion, which may be, for example, digitally signed by a license issuing authority, includes characteristic information of a digital content decryption key required to access the digital content controlled by the license. The unvalidated portion includes the digital content key itself, encrypted using an encryption key associated with a player entitled to use the license.
