我正在尝试从欧姆龙 708-BT 血压监测仪读取数据，该监测仪已通过 continua 健康联盟认证。我正在关注这个例子 of a Bluetooth HDP App .我设法连接到设备并以字节格式检索数据，但无法解析数据以获取所需的值。我试图遵循此 PDF 第 19 页指定的 IEEE 血压规范.
这是添加到上面链接的示例代码中的代码。

数据的十六进制表示如下。我相信这些数据包含血压值的值，但可能是错误的。我相信这是唯一的原因是因为在上面链接的 PDF 中，数据将以十六进制值 e7 开头。

最佳答案
我设法解决了这个问题。我遇到的主要问题是我只读了一个血压读数然后一直按上传。这确实会上传一些关于显示器的信息，但不包括血压读数。知道这一点后，我还有许多其他较小的错误需要解决，但没有什么太复杂的。最终工作服务的代码如下。

我有一个字符串input="maybe(thisis|thatwas)some((nice|ugly)(day|night)|(strange(weather|time)))"Ruby中解析该字符串的最佳方法是什么？我的意思是脚本应该能够像这样构建句子:maybethisissomeuglynightmaybethatwassomenicenightmaybethiswassomestrangetime等等，你明白了......我应该一个字符一个字符地读取字符串并构建一个带有堆栈的状态机来存储括号值以供以后计算，还是有更好的方法？也许为此目的准备了一个开箱即用的库？
我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i
我正在使用ruby1.9解析以下带有MacRoman字符的csv文件#encoding:ISO-8859-1#csv_parse.csvName,main-dialogue"Marceu","Giveittohimóhe,hiswife."我做了以下解析。require'csv'input_string=File.read("../csv_parse.rb").force_encoding("ISO-8859-1").encode("UTF-8")#=>"Name,main-dialogue\r\n\"Marceu\",\"Giveittohim\x97he,hiswife.\"\
我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么？ 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设？ 关于java-等价于Java中的RubyHash，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/22737685/
有时我需要处理键/值数据。我不喜欢使用数组，因为它们在大小上没有限制(很容易不小心添加超过2个项目，而且您最终需要稍后验证大小)。此外，0和1的索引变成了魔数(MagicNumber)，并且在传达含义方面做得很差(“当我说0时，我的意思是head...”)。散列也不合适，因为可能会不小心添加额外的条目。我写了下面的类来解决这个问题:classPairattr_accessor:head,:taildefinitialize(h,t)@head,@tail=h,tendend它工作得很好并且解决了问题，但我很想知道:Ruby标准库是否已经带有这样一个类？ 最佳

我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java，并成功地将它与另一个Java包一起使用，但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www
